Designers Should Code: Build an App From Scratch

,

A breakdown of a simple app, from UI design to deployment, that shows off why coding is a magic tool for designers.

Figma, Adobe XD, Photoshop, Wacom Tablet, sketchbook… all tools for interfaces and web designers, yes? Take 2 minutes, and try to remember why you want to become a designer and why you enjoy designing stuff.

Chances are it’s because you like to create; you’re a creative person. Maybe you started with artistic experiences as a child, then turned that creative energy into problem-solving while continuing to express it visually: You became a designer, a creative problem solver.

Today, I’ll try to show you how coding is an underrated tool to express your creative problem-solving mindset by building a real SVG generator from scratch. So let’s get into it!

Step 1: Don’t get an idea; solve a problem

We didn’t go into deep business considerations here, but seeing problems you face and deciding to solve them yourself is a great way to start.

During client work, I needed some SVG waves for illustrations. So I looked for a wave generator: There were a ton of wavy colorful wave generators with parametric inputs but no simple, perfect sine waves generator. I decided to draw it on my math tool GeoGebra and then export it to SVG.

Okay, but not fast. And we like to get our jobs done quickly. But wait… Why don’t we create a perfect sine waves generator? Without equations & boring math software to open, just a curve and an export button. You got it, now let’s design it.

Quick tips: If you are looking for a problem, look for memes in your field. They always show a deep, painful, well-known problem.

Step 2: Design the solution simple as possible

Two main rules: First rule, think about who will use it; the second rule, predict what they expect from how it works. So who? Front-end developers. What are they waiting for? A curve that can be edited with direct feedback and an export button.

Wireframe design

High-Fi design

A quick tip: You can grab the Figma design of the app for more technical tips on the design.

Step 3: Build it for real

As a designer, stopping at step two is perfectly fine. But imagine if you could build what you design! You already know you can create everything you want.

You can see coding as a way to translate your UI that will surely end with a .com application that is usable by everyone. This is why “best languages” don’t matter; coding is just a tool to express your creativity and build stuff for others. And as a designer, a creative person, this might sound…interesting.

UI to functionnal app

UI to functional app

Every web app interface can be translated from UI design to code with HTML/CSS/JS. There is how we can see the role of each of those 3 “languages”:

HTML: I want a button.

CSS: I want my button to look rounded.

JS: I want something to happen when I click on my button.

To build our app, I’ll use Svelte. Svelte is a JavaScript compiler that allows us to use all those three “languages” in one place. So, let’s see how code can translate our UI to functional things.

HTML button code

“Hey web browser, I want a button named “exportButton” and everything in a function named “downloadSVGpath” to be carried out when someone clicks on the button :) Thanks”

CSS style button code

“Hey web browser, I want you to apply these style rules to my basic HTML button: I want a beautiful rounded corner at 16px, a mouse pointer when we hover it, I don’t want any borders, but I want a cool color gradient as a background color. Then, I want the font inside the button to have its color set to #fcfcfc and use the Inter typeface (bold, please). Like my Figma design, I also want to center stuff in the button and add padding. Oh, and add a subtle shadow :) Thanks.”

Drawing SVG curve function

“Hey, web browser, each time our slider moves, I want to run this function: I want you to draw a curve inside a frame that I have defined inside my HTML code. I also want my curve stroke to look rounded at each cap and have a color and width I’ve defined inside variables. You will take the sine function parameters from the stored values of the sliders. Finally, while your x variable hasn’t reached the total width in the x-axis of our frame, you will solve the y-axis point position of the sine equation and draw the curve :) Thanks.”

Quick tips: You can grab the source code files of the app to explore them.

Summary

  • Coding is just a tool that allows us to translate our very visual metaphors into something that everybody can use. How cool is that?!
  • Coding helps us to envision our design goals and forces us to see beyond the visual range: how is my button will be supposed to work? How does it look when hovering? How my popup modal can be designed for mobile devices?
  • Coding allows us to create the weird idea we designed “just for fun” instead of pushing the design case study into our portfolio under the “personal project” tag.
  • Coding shows us how much work is required to achieve what we designed. So we can better understand our design clients’ needs, challenges, and resource management.
  • Coding is flexible. You can replicate the Netflix website pixel perfect with pure HTML/CSS, the Vue Framework, or any other Web framework.

Understanding Cross Browser Testing and Responsive Testing

,

Introduction

The Internet is inevitable in the current time. It is everywhere, and the entire world depends on it to function, perform day-to-day activities and stay connected with people from different corners. Gone are the days when testers only chose to create websites for selected browsers and hardly faced issues maintaining a website on a few browsers. As the technology matured, many significant players entered the browser market. Even the users evolved, became tech-savvy, and improved their browsing habits. Now was a time when businesses were in critical need of cross-browser testing and responsive testing to stay ahead of the competition. Cross-browser testing focuses on the website’s overall functionality; responsive web testing verifies the look and feel of the web application. Cross-browser testing deals with the analysis of the web browsers that their users use, and responsive testing deals with the devices where the company’s user base visits the websites. Let us shed some light and understand cross-browser and responsive testing in detail.

What Is Cross Browser Testing?

We all know that testing cross-browser compatibility of websites « is of utmost importance. It helps understand how stable your web application is across various technologies, browsers, operating systems, and devices. The adoption of cross-browser testing is to provide a better user experience irrespective of which browser-OS-device combination your users use to access your website. In cross-browser testing, the testers generally validate the web application’s functionality and ensure its user-friendliness and performance are up to the mark across the web browsers. Businesses can also take the help of cloud-based automated cross-browser testing tools to have access to a wide range of real devices to test their web and mobile applications. Different browser engines render websites differently; even the version of each browser causes the code uniquely. It means the code behind the websites is read differently by every browser. So, various cross-browser testing strategies are critical for website accessibility. It is how different browsers render a web page:

Blink a LED on a Raspberry Pi With Vaadin

,

As I’m becoming a senior developer in terms of age, I’ve transitioned from one language to another. One of my main interests has always been clean, easy-to-understand UIs (User Interface). That journey started for me with Director (to create multimedia CD-ROMs), Flash website animation, and Flex Rich Internet Applications (= « Flash on steroids »). When I started developing with Java over 10 years ago, we had some projects with the early versions of Vaadin and JavaFX. As I went on with serverside applications, I only continued with JavaFX for some personal and side projects and loved the way you can create a UI both with XML (FXML actually) and code, exactly the same approach I loved with Flex. Since then, my love for Java and JavaFX only grew and it’s still my major programming environment.

But JavaFX has one missing piece: running it in the browser… Yes, JPRO can do this, but it needs a license and a dedicated server. And yes, there are some projects ongoing to bring JavaFX fully to the browser, but they are ongoing and not mature yet… Let’s look at another approach: Vaadin Flow and run it on a Raspberry Pi to control a LED and show the state of a button.

Things We Still Do, Twenty Years Onward

,

Joel Spolsky’s once prolific blogging output dried up years ago, but Things You Should Never Do, Part I is still a classic after 22 years. He wrote it as an outsider’s postmortem following the first beta release (6) of Netscape’s browser, three years after the previous major release 4. There never was a version 5. The team had decided on a full rewrite, and the resulting delay probably cost them their competitive advantage over Microsoft’s Internet Explorer. 

“If Netscape actually had some adult supervision with software industry experience, they might not have shot themselves in the foot so badly”, he closes.

WordPress Website Analysis: Before & After ImageEngine

,


WordPress is by far the world’s most popular CMS. Not only does it dominate the CMS market with a 64% market share, but it also powers 39.6% of all websites. It has taken the internet by storm by democratizing the web for all. Now, anyone can build, manage, and host a successful website without needing a college degree or coding expertise.

However, while WordPress is great at managing many technical aspects, it still can’t do everything for you. Built mostly on PHP, there are often concerns regarding how performant WordPress is. And, with performance impacting everything from bounce rates to SEO rankings to conversions, it’s something that should be on your radar too.

If you don’t know it yet, images are one of the main causes of slow-loading websites. In recent years, WordPress has stepped up its efforts to try and help users with image optimization out-of-the-box.

Still, as we’ll show, it’s not a total solution, and there is still plenty you can do to deliver better experiences on your WordPress website through image optimization.

What is WordPress Image Optimization? Why is it Important?

Simply put, image optimization is anything you do to make images load faster on your website pages. Almost all websites that use images can benefit from some form of image optimization, even those using WordPress.

Why?

Well, performance is a hugely significant factor when it comes to the competitiveness of your website today.

Google has also made performance an increasingly important factor when it comes to SEO rankings. In fact, performance is a direct ranking signal that carries significant weight.

Google’s Page Experience Update that went live in 2021 has been the biggest move in that direction yet. Soon, Google might even use visual indicators in SERP results to distinguish high-performing websites from the rest.

In Google’s own words, “These signals measure how users perceive the experience of interacting with a web page and contribute to our ongoing work to ensure people get the most helpful and enjoyable experiences from the web.”

So, Why Should We Target Images For Performance Optimization?

According to Google, images are the largest contributor to page weight. Google has also singled out image optimization specifically as the factor with the most untapped potential for performance optimization.

This problem isn’t going away soon. According to data by the HTTP Archive, there are roughly 967.5 KB bytes of image data on desktop web pages and 866.3 KB of image data on mobile pages. This is an increase of 16.1% and 38.8%, respectively, over the last five years.

Thanks to popular e-commerce tools like Woocommerce, it’s estimated that up to 28% of all online sales happen on WordPress websites.

And don’t forget, images are both a key part of conveying information to the user and integral to the design of your website. If they take significantly longer to load than your text, for example, it will negatively impact the user experience in a variety of ways.

In summary, optimized images help your WordPress website by:

  • Improving user satisfaction.
  • Improving various traffic metrics, like bounce rates, time-on-page, etc.
  • Boosting your SEO rankings.
  • Contributing to higher conversions (and sales).

How Does Image Optimization in WordPress Work?

WordPress is so popular because it’s a CMS (content management system) that allows anyone to build, design, and manage a website without any coding or advanced technical experience. Advanced features can be installed with just a few clicks, thanks to plugins, and you rarely have to touch the code behind your website unless you want to make some unique modifications.

In short, using a CMS like WordPress shields you from many of the day-to-day technicalities of running a website.

WordPress Image Optimization: What It Can Do

As we mentioned, one of the main reasons WordPress is so popular is because it takes care of many of the technical aspects of running a website. With that in mind, many think that WordPress should also automatically take care of image optimization without them having to get involved at all.

Unfortunately, that’s not really the case.

True, WordPress does offer some built-in image optimization. Whenever you upload an image to WordPress, it currently compresses the quality to about 82% of the original (since v4.5).

In v4.4, WordPress also introduced responsive image syntax using the srcset attribute. This creates four breakpoints for each image you upload according to the default WordPress image sizes:

  • 150px square for thumbnails
  • 300px width for medium images
  • 768px max-width for medium_large images
  • 1024px max-width for large images.

Here you can see an example of the actual responsive syntax code generated by WordPress:

<img loading="lazy" src="https://bleedingcosmos.com/wp-content/uploads/2021/12/33-1024x683.jpg" alt="" class="wp-image-9" width="610" height="406" srcset="https://bleedingcosmos.com/wp-content/uploads/2021/12/33-1024x683.jpg 1024w, https://bleedingcosmos.com/wp-content/uploads/2021/12/33-300x200.jpg 300w, https://bleedingcosmos.com/wp-content/uploads/2021/12/33-768x512.jpg 768w, https://bleedingcosmos.com/wp-content/uploads/2021/12/33-1536x1024.jpg 1536w" sizes="(max-width: 610px) 100vw, 610px">

Depending on the screen size of the device from which a user visits your webpage, WordPress will let the browser pick the most appropriately sized image. For example, the smallest version for mobile displays or the largest for 4K Retina screens, like those of a Mac.

While this may seem impressive, it’s only a fraction of what can be achieved using a proper image optimization solution, as we’ll show later.

Lastly, WordPress implemented HTML native default lazy loading for all images starting with version 5.5.

So, in short, WordPress offers the following image optimization capabilities baked-in:

  • Quality compression (limited)
  • Responsive syntax (up to 4 breakpoints)
  • Lazy loading

WordPress Image Optimization: What it Cannot Do

There are other issues many have with both the implementation of image compression and responsive syntax as it’s used by WordPress. This leads to some users even purposefully deactivating WordPress’ built-in image optimization so they can fully take control of it themselves.

Here are some of the reasons why:

  • WordPress uses a very basic form of quality compression. It does not use advanced technologies like AI and machine learning algorithms to compress images while maintaining maximum visual quality. It’s also lossy compression, so the quality is lost for good. You can clearly see the difference between an original HD image and the compressed version created by WordPress.
  • WordPress only compresses most images by up to 20%, while advanced image optimization tools can reduce all image sizes intelligently by up to 80%.
  • Responsive syntax can provide significant performance improvements over simply uploading a single HD image to be served on all devices and screens. However, it’s still only limited to a set number of breakpoints (typically 3 or 4). Since it’s not dynamic, a whole spectrum of possible image sizes is not created or used.
  • Responsive syntax code is not scalable and can quickly lead to code that’s bloated, messy, and hard to read.
  • WordPress doesn’t accelerate image delivery by automatically caching and serving them via a global CDN, although this can be done using other tools.

Another important optimization feature that WordPress does not have is auto-conversion to next-gen image file formats. Different image formats offer different performance benefits on different devices. Some formats also enable higher levels of compression while maintaining visual fidelity.

Next-gen formats like WebP, AVIF, and JPEG-2000 are considered to be the most optimal formats on compatible devices. For example, until recently, WebP would be the optimal choice on Chrome browsers, while JPEG-4000 would be optimal on Safari browsers.

However, WordPress will simply serve images in the same formats in which they were originally uploaded to all visitors.

How to Measure the Image Performance of a WordPress Website?

As the undisputed king of search engines, we’ll base most of our performance metrics on guidelines established by Google.

Along with its various performance updates, Google has released a number of guidelines for developers as well as the tools to test and improve their websites according to said guidelines.

Google introduced Core Web Vitals as the primary metrics for measuring a web page’s performance and its effect on the user experience. Thus, Core Web Vitals are referred to as “user-centric performance metrics.” They are an attempt to give developers a testable and quantifiable way to measure an elusive and abstract concept such as “user experience.”

Combined with a number of other factors, Core Web Vitals constitute a major part of the overall page experience signal:

You can find a complete introduction to Core Web Vitals here. However, they currently consist of three main metrics:

  • LCP (Largest Contentful Paint): The time it takes the largest above-the-fold element on your page to load. This is typically a full-sized image or hero section.
  • FID (First Input Delay): The delay from the moment a user first interacts with an element on the page until it becomes responsive.
  • CLS (Cumulative Layout Shift): The visual stability with which the elements on a page load.

Here is an illustration of how these metrics are scored:

While these are the three most important metrics to optimize, they are not the only ones. Google still measures other metrics like the FCP (First Contentful Paint), SI (Speed Index), as well as the TTFB (Time to First Byte), TBT (Total Blocking Time), and TTI (Time to Interactive).

A number of these metrics are directly affected by the images used on your web pages. For example, LCP, FCP, and SI are direct indicators of how fast the content of your web page loads and depends on the overall byte size of the page. However, it can also indirectly affect FID by keeping the main thread busy with rendering large amounts of image content or the perceived CLS by delaying the time it takes large images to load.

These metrics apply to all websites, whether they are custom-made or built using a CMS like WordPress.

When using tools like Lighthouse or PageSpeed Insights, you’ll also get scored based on other flags Google deems important. Some of them are specific to images, such as properly sizing images and serving images in next-gen formats.

If you only use built-in WordPress image optimization, you’ll get flagged for the following opportunities for improvement:

Some of the audits it will pass, however, are deferring offscreen images (lazy loading) and efficiently coding images (due to compression):

A Better Way to Optimize WordPress Images: ImageEngine

Billions of websites are all vying for prime real estate on Google SERPs, as well as the attention of an increasingly fussy internet-using public. Every inch matters when it comes to giving your website a competitive advantage.

So, how can you eliminate those remaining performance flags and deliver highly optimized images that will keep both your visitors and Google happy?

Sure, you could manually optimize images using software like PhotoShop or GIMP. However, that will take you hours for each new batch of images. Plus, you still won’t benefit from any automated adaptive optimization.

A more reasonable solution in today’s fast-paced climate is to use a tool developed specifically for maximum image optimization: an image CDN like ImageEngine.

ImageEngine is an automated, cloud-based image optimization service using device detection as well as intelligent image compression using the power of AI and machine learning. It can reduce image payloads by up to 80% while maintaining visual quality and accelerating delivery around the world thanks to its CDN with geographically dispersed PoPs.

Why is ImageEngine Image Optimization Better Than WordPress?

When making a head-to-head comparison, here are the reasons why ImageEngine can deliver better performance:

  • Device Detection: ImageEngine features built-in device detection. This means it picks up what device a visitor to your website is using and tailors its optimization strategy to what’s best for that specific device.
  • Client hints: By supporting client hints, ImageEngine has access to even more information regarding the device and browser to make better optimization decisions.
  • Next-gen formats: Based on optimal settings, ImageEngine automatically converts and serves images in next-gen formats like WebP, AVIF, JPEG2000, and MP4 (for GIFs).
  • Save data header: When a Chrome user has save-data mode enabled, ImageEngine will automatically compress images more aggressively to save on data transfer.
  • CDN with dedicated edge servers: ImageEngine will automatically cache and serve your optimized image assets using its global CDN. Each edge server has device awareness built-in to bring down latency and accelerate delivery. You can also choose to prioritize specific regions.

So, the key differentiator is that ImageEngine can tailor optimizing images for what’s optimal for each of your visitors. ImageEngine is particularly good at serving mobile visitors thanks to WURFL device detection, which can dynamically resize images according to most devices and screen sizes in use today. As of now, this is a completely unique capability that none of its competitors offer.

It allows for far better and more fine-tuned optimization than WordPress’ across-the-board approach to compression and responsive syntax.

If you want, you could turn off WordPress responsive syntax and compression, and you would still experience a performance increase using ImageEngine. However, ImageEngine also plays nice with responsive syntax, so it’s not completely necessary unless you want to serve the highest-fidelity/low-byte-size images possible.

How Does ImageEngine Work with WordPress?

The process ImageEngine uses to integrate with WordPress can be broken down into a few easy steps:

  • Sign up for an ImageEngine account: ImageEngine offers three pricing plans depending on the scale and features you need as well as a no-commitment 30-day free trial.
  • Specify your image origin: This tells ImageEngine where to find the original versions of your images. For a WordPress website, you can just use your domain, e.g., https://mywordpresswebsite.com. ImageEngine will then automatically pull the images you’ve uploaded to your WordPress website.

  • Copy the Delivery Address: After you create an account and specify your image origin, ImageEngine will provide you with a Delivery Address. A Delivery Address is your own unique address that will be used in your <img> tags to point back to the ImageEngine service. Delivery Addresses may be on a shared domain (imgeng.in) or customized using a domain that you own. A Delivery Address typically looks something like {random_string}.cdn.imgeng.in. If your images are uploaded to the default WordPress folder /wp-content/uploads/, you can access your optimized images from ImageEngine simply by changing your website domain. For example, by typing {imageengine_domain}.cdn.imgeng.in/wp-content/uploads/myimage.jpg into your browser, you’ll see the optimized version of that image. Just press the copy button next to the Delivery Address and use it in the next step configuring the plugin.

  • Install the ImageEngine Optimizer CDN plugin: The plugin is completely free and can be installed just like any other plugin from the WordPress repository.
  • Configure and enable ImageEngine Plugin in WordPress: Just go to the plugin under “ImageEngine” in the main navigation menu. Then, copy and paste in your ImageEngine “Delivery Address,” tick the “Enabled” checkbox, and click “Save Changes” to enable ImageEngine:

Now, all ImageEngine basically does is replace your WordPress website domain in image URLs with your new ImageEngine Delivery Address. This makes it a simple, lightweight, and non-interfering plugin that works great with most other plugins and themes. It also doesn’t add unnecessary complexity or weight to your WordPress website pages.

ImageEngine vs Built-in WordPress Image Optimization

So, now let’s get down to business by testing the performance improvement you can expect from using ImageEngine to optimize your image assets.

To do this test, we set up a basic WordPress page containing a number of high-quality images. I then used PageSpeed Insights and the Lighthouse Performance Calculator to get the performance scores before and after using ImageEngine.

Importantly, we conducted this test from a mobile-first perspective. Not only has mobile internet traffic surpassed desktop traffic globally, but Google themselves have committed to mobile-first indexing as a result.

Here is a PageSpeed score using the Lighthouse calculator for WordPress with no image optimization:

As we can see, both Core Web Vitals and other important metrics were flagged as “needs improvement.” Specifically, the LCP, FCP, and TBT. In this case, both the LCP and FCP were a high-res featured image at the top of the page.

If we go to the opportunities for improvement highlighted by PageSpeed, we see where the issues come from. We could still save as much as 4.2s of loading time by properly resizing images and a further 2.7s by serving them in next-gen formats:

So, now let’s see how much ImageEngine can improve on that.

The same test run on my WordPress website using ImageEngine got the following results:

As you can see, we now have a 100 PageSpeed score. I saved roughly 2.5s on the SI (~86%) as well as roughly 1.7s on the LCP (~60%). There was also a slight improvement in the FCP.

Not only will you enjoy a stronger page experience signal from Google, but this represents a tangible difference to visitors regarding the speed with which your website loads. That difference will lead to lower bounce rates, increased user satisfaction, and more conversions.

There was also a 53% overall reduction in the total image payload. This is impressive, considering that it’s on top of WordPress’ built-in compression and responsive syntax.

Conclusion

So, as someone with a WordPress website, what can you take away from this?

Well, first of all, WordPress does feature some basic image optimization. And while not perfect, it should help you offer reasonable levels of performance, even if you use a lot of image content.

However, the caveat is that WordPress applies aggressive, across-the-board compression, which will lead to a noticeable reduction in visual quality. If you use WordPress for any type of website where premium quality images are important, this is a concern — for example, as a photography portfolio, exhibition, or image marketplace like Shutterstock.

By using ImageEngine, you can reduce image payloads and accelerate delivery even further without compromising too harshly on visual quality.

Chatbots Are Here To Stay

Chatbots have been around for a long time and based on the global chatbot market size (and the expected growth), they will stick around for a long time and gain importance. In the past, they’ve rarely met customer expectations or provided much positive experience. However, over the last few years, advances in conversational AI have transformed how they can be used. Since chatbots offer a wide range of applications, in certain cases, they become responsible for collecting and protecting personal information as well. 
Consequently, they are a great attraction for hackers and malicious attacks too. The responsibility of ensuring chatbot security has become more evident after the introduction of GDPR in Europe. As statistics show that this technology will be a determining factor in our lives, security testing must also become part of our daily tasks, so that these chatbots can be used with confidence.

Security Risks, Threats, and Vulnerabilities                 

The words risk, threat, and vulnerability are often confused or used interchangeably when reading about computer security, so let’s first clarify the terminology:

  • Vulnerability refers to a weakness in your software (or hardware, or in your processes, or anything related). In other words, it’s a way hackers could find their way into and exploit your systems.
  • A threat exploits a vulnerability and can cause loss, damage, or destruction of an asset – threats exploit vulnerabilities.                
  • Risk refers to the potential for lost, damaged, or destroyed assets – threats + vulnerability = risk! 
The well-known OWASP Top 10 is a list of top security risks for a web application. Most chatbots out there are available over a public web frontend, and as such, all the OWASP security risks apply to those chatbots as well. Out of these risks, there are two especially important to defend against, as in contrast to the other risks, those two are nearly always a serious threat — XSS (Cross-Site Scripting) and SQL Injection.
In addition, for artificial intelligence-enabled chatbots, there is an increased risk for Denial of Service attacks, due to the higher amount of computing resources involved.

Vulnerability 1: XSS – Cross-Site Scripting

A typical implementation of a chatbot user interface:           

           

  • There is a chat window with an input box.
  • Everything the user enters in the input box is mirrored in the chat window.
  • Chatbot response is shown in the chat window.

The XSS vulnerability is in the second step — when entering text including malicious Javascript code, the XSS attack is fulfilled when the web browser is running the injected code:

 <script>alert(document.cookie)</script>              

Possible Attack Vector

For exploiting an XSS vulnerability the attacker has to trick the victim to send malicious input text. It can be done through one of the following ways:

The Top 5 Form Types to Use in Your Web Design 

,

There are a lot of factors that contribute to a better user experience on a website. Pages need to load quickly to give users peace of mind and efficiency. Navigation must be clear and straightforward, with direct pathways for visitors to follow when finding your contact pages, blog posts, and products. Your colors need to work seamlessly together while providing just enough contrast in the areas that need it most.

Excellent user experience needs to be considered for every part of your website that acts as a touchpoint with a potential customer or user.

One of the most significant touchpoints of all is your forms.

All websites need some form of interactive content to thrive. Users need to be able to do something with the site, whether it’s looking for information with a search bar, contacting a team for a quote, making a booking, or completing a purchase. Forms power the majority of the interactive activities available on websites.

If you know how to master great UX on a form, you can contribute to more meaningful interactions between your brands and their customers. But not all web forms are the same. Here are some of the top types of forms you need to master and how you can optimize them.

The “Opt-In” Form

The Opt-in Form is probably the best-known form in the digital landscape. It’s essentially a form that asks visitors to “opt-in” to a specific offer. Sometimes, this means signing up for a webinar; other times, it’ll be agreeing to an email newsletter or a regular series of blog updates.

Opt-in forms grab attention quickly and ask for something specific from the audience. For instance, this example from HuffPost encourages visitors to “Subscribe to the Morning Email.”

Opt-in forms are all about generating action.

Sometimes, they’re placed at the bottom of a landing page after a company has had a chance to explain precisely what they’re offering. Other times, you’ll find the opt-in form situated on a sidebar of a website, constantly enticing people to “sign up” if they like what they see on a blog post or article.

It’s also common for opt-in forms to appear as pop-ups and exit pop-ups on modern websites. For example, a brightly colored opt-in form that promises an immediate benefit to a customer could encourage them to hand over their details before they abandon your website.

How to Design a Great Opt-In Form

So what kind of best practices go into an excellent opt-in form?

  • Start with simplicity: If you’re asking your visitors to do something, don’t overwhelm them with too big of a request straight away. Keep the form short and simple, so it doesn’t seem like too much extra work for the visitor. Something like “Subscribe to our newsletter” should ask for nothing more than an email. 
  • Highlight the benefits: Most customers won’t want to give you a place in their inbox or the opportunity to interact with them further unless you can offer something in return. Even if you’re asking for something small, like an email address, let the customer know what’s in it for them. In the HuffPost example above, the company highlights that you can wake up to the day’s “most important news.” 
  • Give the visitor the power: Let your visitor know they’re in control here. They want to see that they’re getting exactly what they need from you in exchange for their contact details. This means reassuring them that their email address won’t be used for spam, like H&B Sensors does here: 

The Contact Form 

The Contact Form is another crucial part of building an effective UX for your website – but it’s also an element that web designers and business owners often overlook. When customers decide they want to learn more about a business, they need a quick and easy way to get in touch.

Contact forms need to be easy to find and use on any website. Usually, your user will expect to see a link to the contact form situated somewhere at the bottom of your webpage. It might be called “Contact Us” or “Customer Support.” Avoid anything that would go over the user’s head.

Aside from being easy to track down, your contact form also needs to reassure an audience that they’re making the right decision by getting in touch. Therefore, the content needs to be short, sweet, and authoritative—highlight why the user might contact your company and how they can do so.

Avoid any unnecessary information in the contact form. For example, you don’t need to know your client’s age and their job to answer a question about where their nearest physical branch is. Keep form fields to the point, or you’ll chase customers away.

How to Design a Great Contact Form

Design something personalized but straightforward to make the most of your contact form. Use features like smart content and conditional logic, if possible, to adapt the page to the user’s needs. Dynamic content is becoming increasingly valuable these days. Other best practices include:

  • Set the right expectations: Let your customers know how active you are and how quickly they can expect to hear back from you. Imagery and the right fonts can also set expectations about the kind of communication your audience can expect. For example, this contact page from the Marvel app is fun and playful, like the company itself:

  • Provide multiple options: If your customer doesn’t want to use your contact form, give them another way to get in touch. Ensure the contact page includes information like where to find you on social media and your professional phone number. 
  • Simplify things on your end: To ensure that you can contact your audience as quickly as possible, allow your customers to choose a specific subject that their query is connected to. Allowing them to choose “Sales” or “Order issues” means you can automatically direct the message to the right team member on the back-end. 

The Online Payment Form 

Sometimes, when your customers have seen what you have to offer and they’ve checked out the competition, they decide to go ahead with their purchase. To facilitate this, you’re going to need an online payment form. Online forms ensure that your customers can safely enter their credit or debit card details to purchase whatever you have to offer.

Most payment processing companies like PayPal, Square, and Stripe come with payment forms included, so you can easily embed them into a website in minutes. However, there’s always the option to customize those payment forms.

For instance, ideally, you’ll need a payment form that keeps your customer on the same page, so they don’t have to log into another browser to make their purchase. The fewer transitions your client has to make, the safer they’ll feel.

How to Design a Great Payment Form

When designing any payment form, simplicity and security are the two most important factors. Your customer should be able to enter their information quickly and easily and get through the transaction process without worrying about their details.

Remember to:

  • Keep it simple: The fewer fields the visitor has to fill out, the better. Customers still feel uncomfortable sharing personal information and payment details online. Make the experience as painless as possible. If your client already has an account with your business, you might create a system that automatically fills some of the fields, such as their email address, name, and billing address. 
  • Offer the right integrations: The proper payment forms will integrate with the payment services your customers prefer to use. Options include PayPal, Stripe, Square, Verified by Visa, and Mastercard. Get a developer to integrate the right APIs with your form to give your customers the broadest range of options. 
  • Ensure security: Give customers peace of mind by providing as much security evidence as possible. An SSL certificate that places the padlock on the top of the browser next to the URL is a great way to make customers feel more secure. Integrating verification options so your customers can avoid fraud issues is another significant step. Sometimes just putting logos from the card types you accept on the page will make a customer feel more secure. 

Support Forms

Some companies bundle the contact form and the support form together. Others have a separate support form to get their queries routed directly to the people most capable of helping them. If you want to take the second route, it might be a good idea to design a “help” section on your website where you can locate the support form.

The “Help” section on a site often appears alongside other links on the footer. For instance, it could appear alongside “About” links and “Contact” options. Here’s an example of Hubspot’s Customer Support options:

The best customer support pages come with various ways for clients to help themselves and find answers to their most pressing questions. For example, you might have a search bar where your audience can search for the answers to their queries or a knowledge base full of helpful blogs.

Hubspot allows users to choose between a blog, knowledge base, academy training center, community forum, developer discussion board, and assistance from a certified partner.

How to Design a Great Customer Support Form

Designing a good customer support form is about getting your audience the information they need as quickly as possible. Once again, you’ll need to stick to as few form fields as possible here to avoid angering an already frustrated customer. Also, remember to:

  • Ask for the right information: Find out what the query is about by giving the customer a drop-box menu full of possible topics to choose from. If you need a product reference number or something similar, ask for that at the top of the form, then allow the customer to provide extra information about their query underneath. 
  • Set expectations: Let your customers know when they can expect to get a response to their concerns and provide them with advice on what to do next. For instance, you could invite them to check out your knowledge base while they wait for a response. 
  • Keep it simple: Avoid using technical jargon on your support request forms. Be direct in your requests for summaries of the issue at hand, contact information, and other supplemental data. 

Customer Feedback Forms

According to Microsoft, around 96% of customers say that customer service is crucial in determining their loyalty to a specific brand. Another 52% of global customers believe that companies need to respond to the feedback provided by customers.

To ensure your customer service strategies are on-par with what your customers expect, you need to get feedback from your audience. That’s where a feedback form comes in. Customer feedback forms often appear after a client has finished purchasing on the “thank you” screen. They may also occur after a customer has completed a service interaction online.

Here’s an example of an Apple feedback form:

How to Design a Great Customer Feedback Form

By leaving you feedback, your customer is doing you a massive favor. They’re giving you a chance to learn from your mistakes and improve the service you can give next time around. Feedback is one of the best tools for any business that wants to grow and thrive.

If you want your customers to use your feedback forms, you’ll need to make them as simple as possible. Your customers don’t have time to waste on a complex form.

  • Don’t make any fields mandatory: Don’t stop your customers from submitting a form unless they’ve completed every field. Allow them to enter the information they consider to be the most important, and that’s it. You can even fill some of the form out for your customer, if possible, by entering their name and email address if they’re already a member of your site.
  • Make it mobile responsive: Remember there are around 3.5 billion smartphone users worldwide. You can’t afford to lose feedback because your form isn’t responsive. Every form should look and feel incredible on any device. 
  • Include a rating option: If your customers don’t have much to say about your service, or they’re not wordsmiths, they might prefer a rating option instead. A one-to-five rating system that allows your customer to judge your product or service on a scale of poor to wonderful is a great way to gain quick information. Check out the Uber Engineering example here:

Though you can pre-enter some information on a feedback form to make your customer’s life easier, don’t overstep your bounds. Adding your customer’s email address to the form is fine if they’re already a customer with you. Pre-selecting the “very satisfied” rating above would look presumptuous.

Top Tips to Improve Every Form Design

The online form is an essential part of any web design project, but it’s also frequently overlooked. Unfortunately, without a good set of forms, your customers will struggle to interact with your company in a meaningful way.

When creating any form, remember:

  • Reduce friction: Reduce the friction for your customers by asking as few questions as possible. The less your customer has to answer, the better. If you can pre-populate forms with information like your customer’s name and email address, this could help. 
  • Keep it simple: Make sure that the form is clean and easy to use. Your customers shouldn’t be confused about where to click or how to submit their information. A single-column design is often better than a multi-column option.
  • Be clear in error messages: Don’t just tell your visitors that something has gone wrong. Let them know what they need to do to submit the form successfully. If possible, use inline validation with real-time feedback to let your audience know that you recognize the information they’ve submitted.
  • Keep data secure: Make sure your audience feels safe by letting them know how you will use this information and why you’re asking for it. If you’re asking for an email address, make the benefits of entering that information clear. 
  • Make fields optional: Allow your audience to add more information to a form if they want to – but don’t demand it. Give some freedom to the visitor. 

The better your forms are, the more effective your interactions with customers will be. Remember, it’s not just the face-to-face interactions that your customers judge when making decisions about your business and whether to trust you. Today’s digital world has prompted a new demand for more meaningful virtual experiences.

Your form could be the first interaction you have with a client, whether it’s a contact form, a booking form, or something else entirely. Get that right, and you can improve your chances of your customers coming back to interact with you again later.
