✍️ New Article: Balancing flex items with flex-wrap: balance I explored flex-wrap: balance and flex-line-count and really enjoyed using them. I even made a masonry layout by mixing flex-line-count, round, clamp, and container queries units! 😀 ishadeed.com/article/flex...

Trimming our #CSS with sibling-index() and sibling-count(): "Small changes like this add up. Replacing repetitive selectors with functions like sibling-index() and sibling-count() makes the code easier to read and maintain, and a little more resilient to change." thoughtbot.com/blog/trimmin...

So, I’ve written a bunch of things on how to do certain things with View Transitions, such as optimizing the keyframes or driving a VT by scroll. I noticed I repeat a lot of code throughout those experiments … so I bundled that all up in a package for you. 👉 chrome.dev/view-transit...

💡 CSS Tip! In Anchor Positioning, you can use position-area to place an element relatively to its anchor, but there are 36 different positions !? 👀 No one can memorize them all, so I've created an interactive demo where you can select a position and get its code. css-tip.com/position-area/

With View Transitions now being Baseline Newly available, and the View Transition API consisting of various features, it can be confusing to know what is supported in which browser versions. To help with that, I created this VT Feature Explorer (powered by View Transitions) web.dev/blog/same-do...

CSS uses a complex algorithm to decide how to animate transforms. If you get it wrong, as many folks do, you end up with an unnatural animation. Here's how it works, and how to avoid the pitfalls. jakearchibald.com/2025/animati...

FINE I'LL BLOG MINE jeez. frontendmasters.com/blog/the-coy... Seriously though — this is fun! Critique it!

If you thought we were done with View Transitions, guess again! A feature Chrome is working on, is “Scoped View Transitions”, which allow you to scope a VT to a subtree of the DOM. This unlocks things like concurrent transitions and prevents layering issues. developer.chrome.com/blog/scoped-...

Between the time we launched the original Learn CSS course on web.dev and today, container queries landed in browsers and became Baseline Widely available! It was high time for an update, and we were lucky enough to have the team at OddBird work with us. Enjoy 9 new modules! web.dev/blog/learn-c...

🛠️ New Article: The Basics of Anchor Positioning I wrote an article covering some basics of CSS anchor positioning. Really excited to share this one! 🤩 🔗 ishadeed.com/article/anch...

transform & opacity If you can do your animations with only these then do it. Others will likely cause the below to happen

I've somehow only now realized that if you want to transition between themes, view transitions make it incredibly easy... Translates like I did here are a bit over the top, but clip-path opens up some fun possibilities.

scroll-target-group is coming to Chrome 140 (stable next month)! Building on CSS carousel APIs, scroll-target-group lets you "enhance" elements into scroll markers, enabling you to build this scroll-spy effect in 2 lines of CSS! Makes for a great progressive enhancement! una.im/scroll-targe...

[New blog post] Are CSS Carousels accessible sarasoueidan.com/blog/css-car... In this post, I share some important insights from examining the accessibility of CSS-only carousels that use new features introduced in the #CSS Overflow Module Level 5 spec. #a11y

Can you believe this demo uses NO JavaScript!? I'm trying out 2 new web platform features: 1. popover=hint prevents other popovers from closing when opened (landed in Chrome 133) 2. interesttarget to open the comment details on hover/focus (WIP, origin trial, needs work for touchscreen behavior)

You can achieve the `auto` behavior by using the renewed `attr()` function. Unlike `auto`, it can work with any attribute and it’s also less of a footgun (*) www.bram.us/2025/01/20/c... is a demo that uses `attr()` to set the `view-transition-name`s. (*) See github.com/w3ctag/desig... for details.

As of Chrome 131 you have more options to style `<details>` and `<summary>`. You can now use of the `display` property on these elements, and also use a `::details-content` pseudo-element to style the part that expands and collapses. developer.chrome.com/blog/styling...
