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…

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…

Horizontal Scrolling Containers Are Not a Content Strategy

I should clarify that I am not talking about carousels. That said, because users often consider horizontal scrolling containers to be carousels, I will be talking about carousels. Also, this post is written by a monolingual American. While I discuss localization issues, there’s no way I can get into all…

Check / Uncheck all in a Table

TL;DR: Unless you have user testing results saying otherwise, maybe put a check-all checkbox outside the table. The rest of this post is an awkward mash-up of my posts Don’t Turn a Table into an ARIA Grid Just for a Clickable Row and Check-All / Expand-All Controls with a little…

Where to Put Focus When Opening a Modal Dialog

TL;DR: blanket statements about where to put focus when opening a modal dialog are wrong, including this one. This post is meant to help you, an intelligent and thoughtful and empathetic reader, figure out where you should set focus. The scenarios are non-exhaustive.

Tweaking Text Level Styles, Reprised

In 2017 I wrote Tweaking Text Level Styles (terrible name in retrospect) and I made regular updates over the years. Stop reading it. Remove it from your bookmarks. Unlink it from your posts. Print it onto paper and then burn it. Demo <mark> <del> <ins> <s> Wrap-up The conclusions and…

Mainlining Mains

Sometimes you run into a main landmark where you don’t expect one. Like Main Street USA in Hong Kong Disney. So you grab a snack in a diner that serves no hot dogs. You can buy little American flags in the heart of Hong Kong and clothes telling Hong Kong…

Don’t Wrap Figure in a Link

In my post Brief Note on Figure and Figcaption Support I demonstrate how, when encountering a figure with a screen reader, you won’t hear everything announced at once: No screen reader combo treats the caption as the accessible name nor accessible description, not even for an image that lacks one.…

Brief Note on Figure and Figcaption Support

I am not going to dive into the details of <figure> and <figcaption>. Go read Scott’s 2019 post How do you figure? for an overview. That said, since Scott’s post there has been movement on the AAPI mapping (partly by Scott). Specifically, the <figcaption> element should not provide the accName…
