View Transition List Reordering (with a Kick Flip)
It's pretty straightforward to animate list items into new positions, but there is a few tricks when the specific one you've chosen to move needs a *different* transition.
blur(1px) blur(1px)
I know that you can “chain” the CSS property filter, like: All three of those filters will apply. But somehow I never thought about applying the same filter more than once. That also works, and they don’t override each other, they “stack” (or whatever you want to call it). So here’s some useless bar trivia […]
Satisfies in TypeScript
The `satisfies` keyword allows you to assert that a certain value
CSS Gap Decorations
Microsoft is working on “gap decorations” and have put together a nice playground to explore them, and I had a play. The idea is drawing lines where gaps would be, rather than empty space. It’s really quite well done with lots of control (do they hit the edges or stop short? do they overlap or […]
Custom Select (that comes up from the bottom on mobile)
You've got A LOT of control over the design of select menus now, and it can be done as a progressive enhancement.
Step Gradients with a Given Number of Steps
A deep dive into producing an interpolated
Iterator Helpers Supported Across all Browsers
Feels notable that Iterator helpers have become Baseline Newly available. The gist is that you can map and filter on stuff that was annoying or impossible to before. I’ll copy Jeremy Wagner’s example:
Quantity Query Carousel
:has() makes quantities queries both easier and more powerful. We can alter how a grid is laid out and where the children go. Or, we can just blast it into a carousel.
What Is Developer Advocacy? (2025 Edition)
I thought Ashley Willis did an excellent job explaining the role in What Is Developer Advocacy? (2025 Edition). We’re still here to serve developers. And we’re still doing the messy, meaningful work of bridging the gap between what a company thinks developers want and what developers actually need. I liked the perspective that it’s actually better for […]
Understanding CSS corner-shape and the Power of the Superellipse
The CSS corner-shape property (very new! only in Chrome Canary!) is useful in basic use cases, for advanced shape making, and the superellipse() function is *extra* powerful.
Import Assertions use “with” not “assert” anymore.
I was trying to play with CSS Module Scripts the other day, which are a way to import CSS as a constructable stylesheet using the ESModules syntax. They are Chrome-only so not really something we can generally use (unless you’re building an Electron app or something), but I really like the idea of being able […]
Drawing CSS Shapes using corner-shape
After you've got a `border-radius`, you can control the shape of the corner with `corner-shape`, which unlocks a simpler and more powerful way to make shapes compared to `clip-path()`.
Scope in CSS
We've got @scope in CSS now, and it's got it's uses. But the concept of scope in CSS is a wider idea.
You’re not a front-end developer until you’ve…
A fun list post from Nic Chan where you check off the funny/sad/proud/weird things we do as front-end developers. I don’t know if a higher score is better, but it certainly means you’ve been around the block. I doubt you’ll be able to resist poking around Nic’s site, it’s really fun.
Grainy Gradients
This is about reducing banding effects in gradients by introducing noise. A nice approach is a displacement map using SVG filters.
Jake Archibald on Native HTML Includes
There was a lot of interest in our Why Can’t HTML Alone Do Includes? article. I’d like to point you to my ShopTalk Show conversation where we really get into things more with Jake Archibald.
1fr 1fr vs auto auto vs 50% 50%
There are several different ways to do equal width columns. But some are, uh, more equal than others.
Cursed Knowledge
Fun idea from the team at Immich: Cursed knowledge we have learned as a result of building Immich that we wish we never knew. Stuff like: Fetch requests in Cloudflare Workers use http by default, even if you explicitly specify https, which can often cause redirect loops.
Scroll-Driven Letter Grid
scroll-timelines go from 0 to 100. Many variable fonts axis have similar ranges, like 100 to 900. Surely that's begging for interplay.
The Height Enigma
You might as well really understand height and Josh Comeau has your back here. It’s really quite different than width and perhaps less intuitive. Plus when grid and flexbox get involved, things change.
firstChild can be white space
Just a tiny gotcha.
SVG to shape()
We’ve been trying to make the point around here that the new shape() in CSS is awesome. It’s the powerful <path> in SVG ported to CSS so it can use actual units. It’s probably how path() should have ported to begin with, but c’est la vie. I’ll make the point in this demo. Resize those […]
