A chart showing responses for the question "What frameworks do you use?": - React: 72% - Web components: 36% - Angular: 28% - Vue: 18% - Stencil: 7% - Svelte: 4%

Nice result in @zeroheight.com's 2026 Design Systems Report: report.zeroheight.com#your-tools

Web components are the second-most used "framework" among the respondents.

This makes sense: if you build web components you support all the frameworks. Otherwise, you'd probably only support React.

A two-panel meme featuring characters Bernard Lowe and Theresa Cullen from the show Westworld. In the top panel, Theresa hands Bernard a document labeled "SKILL FILES". In the bottom panel, a close-up shows Bernard looking at the document with a blank expression, captioned: "CLAUDE: DOESN'T LOOK LIKE ANYTHING TO ME".

Finally solving the tooltip arrow usecase with a new CSS property called border-shape

⚠️ WIP early-stage API, timeline TBD, more info coming soon

But it brings a lil tear to my eye to see this working, border & all 🥲

This demo uses anchored container queries + border-shape + a little animation

I don't know who needs to hear this, but when it comes to web performance, if you're measuring in seconds, you're admitting defeat.

Ow yeah! 😎

FYI: you can start using customizable select *TODAY* because it is the perfect progressive enhancement: in browser with no support you get the status quo which is just a regular select (which you can also style up to a certain extent).

`<iframe sandbox />` + SW · Issue #1390 · w3c/ServiceWorker Hi, It seem today implementations across major browsers do not seem to delegate request from the document inside <iframe sandbox="allow-same-origin" src="./inner" /> to the SW controlling the embed...

I often need to make iframes that are controlled by main page and sandboxed. Currently you need a server on a separate origin and lots of tricks to do this.

But this idea would completely fix it:
