CSS code snippet for a container that sets column-height to 250 pixels and column-wrap to wrap.

A couple new column-wrapping features shipped in Chrome 145, like `column-wrap` and `column-height`.

Truly big upgrades for multi-column layouts — here's how you *might* use them... as well as when you might *not* use them.

Try it out! But... not every browser can handle it. This is taking the browser to its limit. Chrome has some issues. Safari too. Bugs will be filed.

@mixin --foo(--arg <length>) { @result { &, & > h2, & + p { width: var(--arg); } } } div { @apply --foo(10em); font-size: 10px; } div > h2 { font-size: 20px; } div + p { font-size: 30px; }

Help the CSS WG by telling us what feels natural to you!

Look at the code in the screenshot. What resulting widths would *you* find least surprising for each of div, div > h2, div + p?

Enough With the Bros For a decade, the trope has been a reliable—and lazy—way to elevate pet peeves into trends.

I don't know, www.theatlantic.com/culture/2026... resonates more with me, it's basically a pejorative.

Do you ever say "bro" to other people? The one time someone said it to me in person (years ago) I found it jarring and unexpected. Maybe I'm too stuck up 😅

In Firefox 148 alone, we were the _first_ to ship:

- Sanitizer API
- Navigation API addHandler
- Iterator zip & zipKeyed

We also shipped pointerrawupdate, ancestorOrigins, trusted types, overflow clip margin…

None of these are in Interop.

A pragmatic guide to browser support by Rachel Andrew It’s tempting to think of Baseline as creating a hard line. If a feature isn’t Baseline, then it’s not ready for use. However, we all know that web development is a world of “it depends”.

If you'd told me that one day I'd be excited about a property called `border-shape`, I wouldn't have believed you.

And yet, here we are. @una.im shared the new CSS property coming to Chrome, which allows you to actually "shape" elements. 👏

translates to ->

<h1>Hello my name is</h1>

HTML might be getting a new type of tag, which… hasn't happened this millennium. Here's the new syntax, and how it works:
