Exciting New Features in Safari 16

,

Apple has released an OS update. Packaged in with it is the latest version of Safari, 16.

Expected to be released ahead of next month’s macOS 13, Safari 16 is packed with updates, making it one of the most capable browsers available.

For web designers, the significance is the forward momentum in web technologies that enable freer design work and fewer hacks to achieve complex layouts. Little by little, CSS recommendations are being implemented to the point that using JavaScript for layout is rapidly becoming as unnecessary as it is disliked.

Some of this was announced in June in the Safari 16 beta. But a lot has been added in the last couple of months. So here’s what’s new in Safari 16 today.

CSS Container Queries

The most exciting addition to Safari 16 is CSS Container Queries.

It is hard to understate how in-demand this feature has been; if you imagine an edit button on Twitter that gifted you crypto every time you corrected a typo, you’d be getting close to how popular this feature is.

Until now, media queries have detected the whole viewport. And so, if you have an element like a card, for example, that needs to change at smaller viewports, you need to calculate the available space and adapt the element’s design accordingly. Unfortunately, this frequently gets out of sync with edge cases causing more than a few headaches for front-end developers.

Media queries are severely restrictive to modern layout methods like Grid that wrap elements automatically because there is no way to detect how the elements are laid out.

Container Queries solve this by allowing you to define styles based on the size of the actual containing element; if a div is 300px wide, the contents can have one design, and if it’s 400px wide, they can have a different design—all without caring what size the whole viewport is.

This is dangerously close to OOP (Object Orientated Programming) principles and almost elevates CSS to an actual programming language. (All we need is conditional logic, and we’re there.)

The latest versions of Chrome, Edge, and now Safari (including mobile) support CSS Grid. Even discounting the rapid decline of Twitter, this is way more exciting than any edit button.

CSS Subgrid

Speaking of Grid, if you’ve built a site with it (and if you haven’t, where have you been?), you’ll know that matching elements in complex HTML structures often results in nesting grids. Matching those grids requires careful management, CSS variables, or both. With CSS Subgrid, grids can inherit grid definitions from a grid defined higher up the hierarchy.

CSS Subgrid has been supported by Firefox for a while but is not yet part of Chrome or Edge. Until there’s wider support, it’s not a practical solution, and using a fallback negates any benefit of using Subgrid. However, its introduction in Safari will surely herald rapid adoption by Google and Microsoft and moves the web forward considerably.

CSS Subgrid is likely to be a practical solution within 18 months.

AVIF Support

AVIF is an exceptionally compact image format that beats even WebP in many instances. It even allows for sequences, creating what is essentially an animated GIF but smaller, and for bitmaps.

AVIF is already supported by Chrome, with partial support in Firefox. Safari now joins them.

AVIF support is one of the more valuable additions to Safari 16 because you’re probably already serving different images inside a picture element. If so, your Safari 16 users will begin receiving a smaller payload automatically, speeding up your site and boosting UX and SEO.

Enhanced Animation

Safari 16 introduces some significant improvements in animation, but the one that catches the eye is that you can now animate CSS Grid.

Yes, let that sink in. Combine Container Queries and animation. The possibilities for hover states on elements are tantalizing.

Safari 16 also supports CSS Offset Path — known initially as CSS Motion Path — which allows you to animate elements along any defined path. This enables the kind of animated effect that previously needed JavaScript (or Flash!) to accomplish.

Chrome, Edge, and Firefox all support CSS Offset Path; the addition of Safari means it’s now a practical solution that can be deployed in the wild.

Web Inspector Extensions

Announced as part of the beta release, Web Inspector Extensions allow web developers to create extensions for Safari, just as they would for Chrome.

Web Inspector Extensions — or Safari Extensions as they’re destined to be known — can be built in HTML, CSS, and JS, so the learning curve is shallow. It’s a good route into app development for web designers.

Because the underlying technology is the same as other browser extensions, anyone who has made a Chrome, Edge, or Firefox extension will be able to port it to Safari 16+ relatively easily. As a result, there should be a rapid expansion of the available extensions.

Improved Accessibility

Accessibility is key to an effective and inclusive web. Be like Bosch: everybody counts, or nobody counts.

When testing a design for accessibility, emulators don’t cut it. In my experience, Safari has some of the most reliable accessibility settings, especially when it comes to Media Queries like prefers-reduced-movement.

Further gains in this field mean that Safari continues to be an essential tool for QA tests.

Reduced Resets

Finally, I want to throw up my hands to celebrate the reduced number of non-standard CSS appearance settings.

For years we’ve been prefacing our style sheets with elaborate resets like Normalize, designed to undo all the assumptions browser developers make about design and the UI preferences of their engineers.

Safari 16 has reportedly “Removed most non-standard CSS appearance values.” How effective this is and how much we can rely on it given the other browsers on the market remains to be seen. However, like many of Safari 16’s changes, it’s a step towards a browser that’s on the developers’ side instead of an obstacle to overcome.

Are Modals In Web Design A UX Disaster?

,

Modals, a nifty little feature that allows you to display different messages at the top of your website, have been touted as extremely useful. Some even claim that they are helpful enough to completely replace the banner ads we all hate so much. But are modals in web design a UX disaster?

If you are unfamiliar with the term, a modal is a dialogue window appearing when a visitor clicks on a hyperlink or hover image.

Suppose you want to collect on-site subscribers or you want visitors to sign up for a freebie. In that case, you can use modals.

However, many web designers – and some website visitors – are against using modals in web design. The main argument is that it affects the user experience. But are modals in web design a UX disaster? Read on to find out.

What Do Modals Do?

Modals often appear as pop-up windows on a web page, requesting a visitor to take action. Most times, they appear following a click on a page element.

Also known as lightboxes, modals isolate the page’s main content. The user will have to complete the action requested by the modal or close it before reassessing the page.

Web designers use modals to capture a visitor’s attention. Since other page contents are inaccessible, a visitor must interact with the modal.

Cons Of Modals In UX

While there are different cons of modals in UX, they all sum up to one con – interruption. When modals appear, they interrupt whatever the user is doing.

Unlike regular pop-ups, users cannot simply ignore the modal and continue browsing. As a result, modals demand immediate attention. 

A user may be interested and decide to interact with the modal. However, if the modal’s content differs from the page’s, the user could forget what they were doing after interacting with the modal.

Furthermore, sometimes modals require action related to information on the page. For example, suppose the user wants to review the information before taking action. In that case, they’ll have to close the modal since the main page is inaccessible.

Statistics show that up to 82% of users dislike pop-ups. Most website visitors aren’t knowledgeable about the technicalities of web design. As a result, they won’t be able to differentiate between regular pop-ups and modals.

After all, modals are a type of pop-up. Some users may consider modals worse since they darken the page’s primary content, making it inaccessible.

Furthermore, people want to visit a website and get what they want immediately. Hence, time is significant. Therefore, modals that require actions that take time can make a website lose visitors.

With all of these cons, you can understand why many web designers say modals are a UX disaster in web design.

Can Modals Be Useful in UX?

In some situations, modals are helpful, and they can improve UX. Many web designers swear on the usefulness of modals, and it’s not difficult to understand why.

Firstly, modals can help simplify a website’s content. For example, a user can immediately exit the page if your website is relatively complex, with lots of content and elements.

You can use a modal to explain the content on the page so that the user doesn’t get confused. Perhaps the modal can display when the user clicks on the back button. The modal can highlight the most critical content on the page and tell the user what to do next.

Secondly, modals are invaluable if you must capture your user’s attention. For example, perhaps you want to display a warning or pass any crucial information that users must know before they continue browsing.

As mentioned before, a user can easily ignore a pop-up, especially if it opens in a new window. However, with modals, the user must at least view the content before they proceed.

Thirdly, a modal can make a web page easier to navigate. It sounds ironic considering the cons, but it’s true if properly implemented. Rather than packing different elements on a web page, you can set some to display as modals.

For example, you can have a page with just text to improve readability. Then, users can click to view visual elements like images and videos as modals.

How To Use Modals the Right Way

Using modals correctly is key to ensuring they don’t negatively affect UX. Here are some ideal situations when you can use modals:

1. Display Warnings

Using modals to give users crucial warnings is ideal, especially if their subsequent actions have serious consequences.

For example, most websites display modals when users click the delete button. Deletion is always critical because, in most cases, it’s irreversible.

A practical example would be an eCommerce website where a user opts to delete items from their cart. You can use a modal to ask the user to confirm before deleting.

2. Input or Collect Information

Modals are effective in prompting users to input information. Sometimes, users must enter specific details before they continue browsing.

A practical example would be a review site where a user wants to submit a review. Before submitting the review, you can use a modal to request the user’s name and other necessary information.

3. Simplify Navigation

As mentioned before, modals can simplify a complex website. In addition, it will help a user navigate better, which is a UX boost.

A practical example would be a news site with many stories and updates. You can use a modal to highlight the day’s trending news stories so that users can visit the web pages with one click.

Conclusion: Are Modals a Disaster in UX?

In conclusion, modals affect a site’s user experience since visitors must interact with them. However, it doesn’t always have to be a negative effect.

Modals become a UX disaster in web design when wrongly used. However, if you follow good practices, modals can improve your website’s user experience.

Generally, only use modals when necessary and in a way that won’t frustrate the users.
