The custom checkbox stays hand-rolled until `::checkmark` actually ships

Andy Bell's new Piccalilli piece previews the ::checkmark pseudo-element and appearance: base, then quietly concedes no browser is working on it. Until that changes, the accessible checkbox is still a label wrapping a real input — not a div.

Safari Technology Preview 252 adds @supports named-feature(), unprefixed user-select and two accessible-name fixes

WebKit's 11 September preview adds a named-feature() function to @supports, exposes CSSConditionRule.supports and CSSMediaRule.matches on the CSSOM, ships the unprefixed user-select property, allows percentage values in text-decoration-inset, and cleans up two accessible-name bugs around display: contents and list markers.

The `headers` attribute has quietly stopped earning its place

Adrian Roselli retested the HTML `headers` attribute against the current crop of screen readers and browsers, and the answer is short: plain, honest table structure carries the meaning by itself, and the attribute is largely useless.

A theme toggle should not overwrite the user's OS choice

Bramus Van Damme argues the third button, System, belongs in a dark-mode toggle. His case is that a two-state control silently maps one of its values back to the OS schedule and overwrites the user's explicit pick.

Whether a dialog closes on outside click is a task question, not a style question

Adrian Roselli sorts modal close behaviour into three buckets — action required, no action required, and weird patterns — and argues you should pick a light-dismiss policy based on what the user came to do, not on how the dialog looks.

The 'blocked aria-hidden' warning is telling you the truth

A new CSS-Tricks piece by Durgesh Rajubhai Pawar argues the browser is right to complain when you hide a focused region — and every popular workaround for the warning just moves the bug somewhere quieter. The fix is a reordering, not a new attribute.

Safari Technology Preview 248 gives progress() a no-clamp option and forwards missing components across analogous color spaces

WebKit's Safari Technology Preview 248 lands two CSS additions worth reading — a no-clamp option on the CSS progress() function and forwarding of missing color components when interpolating between analogous color spaces — plus a pair of accessibility repairs and a small stack of quieter CSS fixes.

aria-expanded has four honest jobs left. The rest belong to the platform.

Steve Frenzel's Piccalilli piece walks every widget that used to demand aria-expanded and shows how many are now better served by <details>, <dialog>, or the popover API. Keep the attribute for menus, navigation, tree views and combo boxes, and drop it everywhere else.

A primary-nav flyout built on `popover`, not `aria-expanded`

Adrian Roselli has rebuilt his 2019 disclosure-widget primary nav on the native HTML `popover` attribute. The rebuild is a clean map of what the platform now carries for you, and where you still need ARIA.

Chrome 150 hands composite-widget arrow keys to the browser

Chrome 150 ships the `focusgroup` HTML attribute, a way to get roving arrow-key focus inside composite widgets like listbox, tablist and toolbar without a line of JavaScript. Adrian Roselli has published script-free demos, and the spec story is still an Open-UI explainer.

Safari Technology Preview 247 lands calc-mix() and clears a scatter of small fixes

WebKit's July 1 preview build adds CSS calc-mix() under its New Features list, plus HTML spec-alignment repairs for align="center" and rel=preload as="json", two VoiceOver-facing accessibility fixes, and a MathML change for underover layout.

Your `<nav>` label already says 'navigation'

Writing 'Primary navigation' on a `<nav>` makes a screen reader announce the word twice. The fix is to trust the landmark and let the label do its actual job.

Your site does not need to function the same on every platform

Bramus argues authors have swapped one cross-browser obsession for a new one — that sites must behave identically across mouse, touch, keyboard and Vision Pro. The piece reframes input-specific affordances as progressive enhancement on the input axis.

`headingoffset` is not the outline algorithm coming back

Firefox has shipped `headingoffset` behind a flag. It quietly fixes a real pain point for reusable components, but it is not, and cannot be, the long-abandoned Document Outline Algorithm in disguise.

ariaNotify() is developer catnip. Treat it like alert().

The new WAI-ARIA 1.3 ariaNotify() method makes screen-reader announcements trivial to fire from JavaScript — which is exactly the problem. The case CSS-Tricks lays out is straightforward: reach for it only where a live region genuinely cannot do the job.

Customizable `<select>` is still a `<select>`: keep the text

WebKit's golden rule for the new customizable `<select>` is the rule we should have been following all along: every option needs real text, even when icons or swatches do the visual work.
