  1. Should a Dialog Close When Clicked Outside?

    Maybe not, but I’ll break these down into three categories because it depends on context and intent. Pretend this post also applies for pressing Esc. Action Required If the user must complete a task that is presented by the dialog, then they should not be able to close it without…

  2. 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…

  3. 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…

  7. WCAG3 Contrast as of April 2026

    I am not speaking on behalf of the W3C nor the W3C Accessibility Guidelines Working Group (AGWG), nor am I a member, nor does anyone who is member know I am writing this, nor do I have any insider knowledge. For years I have seen people, teams, products, organizations, and…

  8. Accessibility Law of Headlines

    Betteridge’s law of headlines states that any headline that ends in a question mark can be answered by the word no. For at least the digital accessibility landscape, I would like to amend it, fork it, whatever it: Any headline that asserts a thing is accessible is wrong. Yes, that…

  9. Your Browser Can Already Speak a Page

    Users can customize the features built into the browser, something not often available from third-party approaches. Is an “AI” company offering to provide spoken versions of your pages for users? Is an overlay company promising to make your content more accessible by its overlay speaking it? Is some…

  10. 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…
