I thought about things that have happened in CSS in 2025 and what I think you should probably know. Then I blogged it. frontendmasters.com/blog/what-yo... It's not *everything* — it's my own curated list.

Flies Listen, I had some flies in the house. I had a party, it was nice having the doors open, some flies got in, and they apparently set up shop. You can't just wait them out. They live like a month. Too long. Not to mention I gotta imagine they were having fly sex in their sweet new pad and…

I used to write about web design. I still do. But I used to, too.

There are a few services out there… for example www.tapelink.io

is there like an established good way of sending your friends a song? I feel like I need a spreadsheet of which music service they use.

Do you think unbending Clippy until he was a long piece of metal would be painful for him. Or do you think it would cause him to feel a great sense of relief

autocomplete="off" translate="no" aria-hidden="false" 🤔

CSS `field-sizing` on a `<textarea>` is obviously awesome. But the horizontal growth using it on an `<input>` is less clearly useful to me. But check out this design pattern I cooked up. I don't hate it. Keeps the name area compact until you need to see more. Just a bit of flexbox wrapping.

Five ways to do "three columns, except when narrow screen, then one". frontendmasters.com/blog/breakpo... Including some fancy newfangled CSS. Which one do you like?

Love seeing @marcgrabanski.com front and center here showing off what his team has built and offering it at a (once-a-year) discount. Frontend Masters is a great place to learn to code better and you pay a fair price for it. www.frontendmasters.com/sale/?utm_so...

I did a fairly straightforward tutorial for the @codepen.io spark this week blog.codepen.io/2025/09/08/c... There have already been some nice forks! toot.cafe/@aardrian/11...

Big fan of the educational demos in @amitsheen.bsky.social's post here about `offset-path`. frontendmasters.com/blog/the-pat...

Totally tuned in to @kevinpowell.co 1000th stream. A bunch of CSS madness. Join! www.youtube.com/live/9aJ2mvT...

Can you `startViewTransition` and force new CSS `random()` values? I mean, kinda. Confuses the heck out of Safari but it'll do it.

I'll be Winging It live with @kizu.dev & @stacykvernmo.com in an hour (11am MT) to talk about future #CSS features like mixins, functions, and masonry! youtube.com/live/ER4APBN...

The only ICE I respect is Internet Comment Etiquette

The library is the most bad ass grift out there. Free books, audiobooks, comics, movies, magazines. It’s feels like shoplifting that benefits society! And when you’re done with it someone else gets to join the heist.

What a lovely interactive blog post? This is SO inspiring 🤩

Chalk Font Kid I used to be able to indentify typefaces in use around in the real world as a kid. My mom would get a kick out of me noticing the same typefaces used by different brands on billboards and stuff as we drove around, as I recall. Nothing like this kid though, jeepers.

woah Zen Browser is *good*. Normally I'm against an app copying another lock stock and barrel, but since Arc jumped ship, I'm all for it here. I'm with @werd.io ... maybe this should just *be* Firefox. werd.io/why-im-all-i...

Scoped View Transitions are ready for testing in Chrome! SVTs expose el.startViewTransition() on HTML elements. The element creates a scope for the transition, ∴ the transition pseudo-elements are affected by ancestor clips and transforms. Multiple SVTs on separate elements can run *concurrently*.

There are so many CSS features rolling out these days but not enough time to experiment myself with everything. That’s why I’m loving @jamessw.com's arbitrary striped table CodePen demo using the new sibling-index() function codepen.io/jamessw/pen/...

In ShopTalk, @chriscoyier.net and @davatron5000.bsky.social tron5000.bsky.social‬ talked about my recent post about RSS, and the curation challenge posed by RSS when you mix together high-volume feeds like The Verge with more infrequent posters (solo bloggers, etc).

Google isn't killing *all* shortlinks now, just some of them. blog.google/technology/d... Isn't that bizarre? Isn't that *more* technical debt? Surely I don't understand all the implications, but it seems like an easy win to spin down the product but let the redirects work forever.

Do all those hustle culture guys whose schedule is like… Wake up at 4am. Eat a tiny meal. Exercise for 15 minutes. Tiny snack. 10 minute nap. Splash around in a bowl of water. Get dressed in practical clothes already laid out. …realize that’s the same agenda as a literal baby?

still kind of a fun idea for a <mark>. codepen.io/chriscoyier/...

But who in their right mind would make a code pen linking to a code pen inside a <code-pen> inside a @codepen.io

If you're new to CSS, one of the best ways to make your life easier is to take advantage of all the CSS debugging features in your devtools. To help, I teamed up with @amitsheen.bsky.social to create a free, 5-part beginner course on getting started with them: devtoolsforbeginners.kevinpowell.co

Just came across this old rudimentary Pen, but it does OK explaining the difference between these ways of handling events that happen a ton. codepen.io/chriscoyier/... (Definitely wouldn't use it for a fixed header these days!)

📢 New blog post: What a diff'rence a semicolon makes: blog.tomayac.com/2025/07/26/w.... Hat tip to André Jaenisch (not on Bluesky?) and @chriscoyier.net for pointing me at (André) and creating (Chris) the Web Development Merit Badges that I'm mentioning in the post.

This article by @chriscoyier.net does a great job of expressing how AI is disincentivizating content creatation. Seems the end game here is bad for everyone, including AI tools, which loose up to date resources to steal... I mean use for research. chriscoyier.net/2025/07/23/i...
