It was late 2020 when I last tested how browsers use CSS display properties to break the semantics of elements. I had been waiting for Safari to fix how it handles display: contents for four years now, and was excited when the announcement came in June. Then I started testing…
At the start of 2016 I wrote Internet Explorer Does Not Go Away Today because back then IE up to version 11 was being retired. But not Internet Explorer 11. I asked an AI (Neural Blender) to give me a picture of the Internet Explorer logo on fire. It’s almost…
I have spent a few years banging on about ensuring scrolling areas on a page are accessible to keyboard-only users. This is partly because the term “keyboard” maps to other input types that we distill to “keyboard” for ease of reference (speech input, sip-and-puff, on-screen keyboards, scanning software, etc.). When…
The proposed WCAG version 2.2 has gone through a bunch of revisions since I covered the first draft in 2020. One new success criterion that persisted is 2.5.8 Target Size (Minimum) at Level AA (its name changed from “Pointer Target Spacing”). For background, WCAG 2.1 introduced 2.5.5 Target Size, mandating…
I made some pointless things again. The First One See the Pen Best viewed in… by Adrian Roselli (@aardrian) on CodePen. A spinning box for each word is not exactly a compelling interface element, I admit, but I based it off this old tweet that was sitting around in a…
Keyboard interaction note for just one control from the entire panoply of HTML controls: A native <button> fires on key down when that key is Enter. If you hold down the Enter key, it continues to fire for as long you hold Enter (or something crashes). A native <button> fires…
If you have little experience with ARIA, screen readers, or testing in general, understanding accessible descriptions can be trickier than understanding accessible names (already confusing for many). I have written explanations so many times for clients and in fora that I opted to put this together so I maybe never…
Data tables need column headers. Monolitten, a granite column of humans (each with a head) at Vigelandsanlegget, a sculpture park in Frognerparken in Oslo, Norway. What they probably do not need is a new set of column headers every few rows, particularly not when they change the meaning of the…
This post serves no purpose other than to demonstrate the fidelity of screen readers when announcing non-emoji Unicode characters when using default settings. There is no judgment on which is correct. This is simply for reference. I grabbed the following tweet and recorded it across common screen readers (WordPress ate…
The title of this post is pretty specific. It relates to the meme on Twitter where users identify a trait or preference that they see as problematic, and identify it as a red flag. The emoji represents the red flag. For example: A stylized red flag Blaming Screen Readers 🚩🚩🚩🚩🚩…
Both Chrome and Firefox support XPath searches when in the DOM view of their dev tools. Because the browser cleans whatever HTML it encounters (closing tags, correcting nesting), XPath can operate on the code as XML. Simple checks like finding a unique ID value can result in multiple hits in…
