Back in March, we published Item Flow, Part 1: a new unified concept for layout, an article about a new idea for unifying flex-flow and grid-auto-flow into a single set of properties under a new item-flow shorthand. We shared some new ideas being developed in the CSS Working Group, discussed how they might fit into Flexbox and Grid, and hinted at the implications for future layouts. Here’s a refre
StyleX v0.15.0 introduces significant improvements to media query handling, dynamic styles optimization, and improvements to the linter, types, and documentation. Media query orderingPreviously, media queries within a style property were applied in a predetermined sorting order. This often meant that the order you authored the queries did not match how they were applied, so we recommended manuall

There is only one item on my CSS wishlist for 2025: a slower pace! After years of rapid innovation, now feels like the right time for browser vendors to take a beat to consolidate, fix browser inconsistencies, and let the rest of us catch up. After all, we might've heard about subgrid, :has(), scroll-driven animations, and all the other recent CSS improvements – but how many of us can say that we'

I recently made an experiment about Proximity Reactions. The idea was to create an interactive effect according to the mouse position relative to elements. Then I made a less JavaScript, more CSS version where the only thing JavaScript does is to pass the mouse position into a couple of CSS custom properties. That’s it. All the heavy lifting happened inside the CSS itself, safely away from the Jav
It’s been possible to create gorgeous layouts on the web for decades, but often refining the details to perfection can take a lot of effort. Arguably too much effort, and developers just don’t have the time. Happily, the last few years of CSS have seen a lot of new tools, sometimes very simple tools, that when used in a smart fashion suddenly make polishing graphic design details incredibly easy.
Investigating performance of Tailwind vs Linaria frameworks, with a focus on initial load and interaction performance. What's your position on Tailwind? Love or hate? Seems to be no in-between for that one. Even if you've never used it, you probably heard of it by now. It's the second most popular UI framework out there after all, and the source of lots of hype in certain corners of the internet.
Browsers are starting to roll out changes in default UA styles for nested section headings. Developers should check that their sites don't rely on UA styles for certain cases to avoid unexpected results and failing Lighthouse checks. In this post, we'll have a look at what the incoming changes are, how to identify if it's an issue on your pages, and some hints for conformant and better-structured

CSS Grid and Flexbox brought incredible layout tools to the web, but they don’t yet do everything a designer might want. One of those things is a popular layout pattern called “masonry” or “waterfall,” which curren
