My Interop 2027 Picks

Interop 2027 is gathering votes and the deadline is 19 November 2026. For the second year now, Firefox made a page to let you rank your Interop 2027 choices. Which I’ve now done. I narrowed it down to fifteen, though getting there was oddly difficult. It seems the top three…

Decorative Images…

…aren’t a thing. Three hand-drawn lines curling together like an S or three skinny snakes trying to spoon. At least not as far as people are concerned. Yes, this is an absolutist take, but sometimes it’s necessary to take the absolutist position to force someone to justify their own reasoning.…

Support for `headers` Attribute

This post only covers the headers attribute in HTML tables (ARIA has no headers equivalent). My 2022 post Accessible Cart Tables? showed headers attribute support was poor. In my 2023 post Avoid Spanning Table Headers I didn’t use headers because I knew support was poor. For this post I merged…

Link + Popover Navigation

This is a redress of my 2019 post Link + Disclosure Widget Navigation, except (as the title implies), I’ve modified it to use native HTML popovers instead of ARIA or HTML disclosure widgets. Popover has the benefit of using appropriate HTML structure and semantics while removing the need for scripting…

Focusgroup Tests

Chrome 150 has landed support for focusgroup, a feature proposed by Open-UI and not yet in WHATWG HTML as anything more than a feature request. Open-UI has outsized representation from Google and Microsoft folks, so it’s no surprise Chrome would implement it first. “FOCUS!” by Metro Centric, CC BY 2.0;…

headingoffset is Not the Document Outline Algorithm

Hi, just me heading off some bad advice I’m starting to see in developer venues. Background The proposed Document Outline Algorithm, where headings would automatically reset themselves to the appropriate level based on their position in the DOM structure, was never part of a final HTML specification. It was quickly…

Honoring Mobile OS Text Size

If your users scale the text size in Android or iDeviceOS, that doesn’t always affect the size of text on a web page. It’s a function of browser and authored code, as opposed to a standardized approach. That may be changing. Support The current state of affairs in the three…

You Know What? Just Don’t Split Words into Letters

This is an unplanned part two for Barriers from Links with ARIA. The title reflects my exasperation because this isn’t new, I’ve simply failed to be explicit about it over the last decade or so. In 2012 I vented about TypeButter using <kern style=”letter-spacing: -0.01em;”> for each letter. In 2020…

Barriers from Links with ARIA

Today Temani Afif asked a question: Are the below codes equivalent if we consider all the aspects? (a11y, semantic, something else maybe?) If not, what is missing (or should be changed) in the second code CSS by T. Afif (@css@front-end.social) 22 January 2026, 2:52pm I have my canned response that…

Live Region Support

This post does not discuss whether live regions are good, nor is it a post about the best way to use them. This post only covers how they are exposed to the audience who experiences them — screen reader users. Written by a non-screen-reader user. If you’re here because your…

Talkin’ Tables at A11yTO Conf

Abstract for my session Talkin’ Tables, which I presented in place of another speaker who had to back out the day before: This session will walk through the basics of how to construct an HTML table. More than basic structure, it will talk about support and how it is exposed…
