Accessibility For Everyone by Laura Kalbag Read the book online for free.

My book, Accessibility For Everyone, is now free and online as a website.

accessibilityforeveryone.site

The book was first published by A Book Apart in 2017 but it holds up! It covers web accessibility for designers, developers, content folks, and really everyone who works in tech.

Screenshot of a performance trace in Chrome DevTools with a few additional "Nav*" and "LCP*" markers. Hovering over the "LCP*" shows this is a "Soft LCP" and in the Summary panel when you click on it you see "Soft Largest Contentful Paint" and a "Learn more about Soft Largest Contentful Paint" link.

From Chrome 145 (on general release next week!), DevTools we will start to show so called "soft" navigations and "Soft LCP" in the Performance Panel traces.

These are for SPAs which don't do a full page load, but instead "fake it" by updating the current page and pushing a new history entry.

What I Wish Someone Told Me When I Was Getting Into ARIA — Smashing Magazine [Accessible Rich Internet Applications (ARIA)](https://www.w3.org/WAI/standards-guidelines/aria/) is an inevitability when working on web accessibility. That said, it’s everyone’s first time learning ...

ARIA! It exists and on a long enough timeline you'll need to use it. Here's how to get into the right headspace to do so! #a11y www.smashingmagazine.com/2025/06/what...

How to have the browser pick a contrasting color in CSS Have you ever wished you could write simple CSS to declare a color, and then have the browser figure out whether black or white should be paired with that color?

Have you ever tried using color contrast tools backed by the WCAG 2 contrast algorithm (probably didn’t realize) — and then wonder “WHY IN THE WORLD DOES BLACK ON MEDIUM BLUE PASS WHILE WHITE ON MEDIUM BLUE FAILS?”

You aren’t the only one.

need product differentiation?

overhire a #CSS front-end team and ask them to:
- polish whatever
- add delight wherever

and watch as your product becomes smooth and buttery while everyone else's gather dust and crust

UI is a huge space offering differentiation via quality

and related to this topic, does anyone know if the CSS mask property supports SVG data URIs where the SVG path has a stroke? the stroke isn't rendering. the mask is just expanding to take the area where the stroke should be.

remember to encode SVGs used as data URIs in a CSS mask property or you'll waste time troubleshooting why an old SVG worked but new one doesn't & difference is new has hex color value (with `#`) & other doesn't. browsers will see `#` as fragment identifier & won't render the SVG as the mask at all.

Two cool improvements are coming to <dialog> soon ™️.

- button command/commandfor attributes to open dialogs without JS.
- closedby attribute to enable light dismiss or disable close on esc (etc)

On popover accessibility: what the browser does and doesn’t do

✏️ Maybe you heard people say the `popover` attribute has accessibility “built in”. And you wonder what that actually means.

Me and @scottohara.bsky.social wrote a post to explain what the browser does and doesn't do in terms of accessibility when you use `popover`

There was an API not documented & I spent a bunch of time reading through code & slack threads to try to understand what the difference between two pieces of similar sounding data were. Started using GitHub Copilot and asked it and it gave me the correct answer instantly. 🤯

CSS - Cascading Sips of Sangria - Front End Happy Hour CSS has been quickly evolving. In this episode, we are joined by Estelle Weyl and Eric Meyer to explore the new properties that are now available.

Oh my gosh, oh my gosh! We got to chat with Estelle Weyl & @meyerweb.bsky.social about CSS on the latest episode of Front End Happy Hour. They have both contributed so much to the community & I've learned a ton from them over many years, so what an honor!
