The world wide web has officially lasted 30 consecutive years, which means it’s catching up to its parent, the Internet, which itself is bearing down on 50. That’s an important distinction. The Internet is not the web; it is the foundation on which the web was born. In honor of…
HTML5 gives us form field validation for free. The problem is that the default messages browsers provide are not always useful and typically do not work with assistive technology. I made an example on CodePen that uses an email field (type=”email”), is required (required), and uses a pattern to restrict…
The pun in the title is that some people pronounce the a11y numeronym as “alley”. That makes the full title sound like uncanny valley, the concept of human-looking things seeming almost, but not quite, human and therefore creepy. In accessibility, the same thing can happen.

A few years ago I made a Venn diagram using floats and absolute positioning. It was fine. Nothing to really brag about, but it got the point across. I had use for CSS shapes in a project and wanted to play around beyond what the project itself allowed. I decided…
Web developers around the world have celebrated Saturnalia solstice Isaac Newton’s birthday Christmas with advent calendars covering web-related topics. As a result, you may recognize some of the ones listed below. Every year I miss a few on day one, so add a comment or tweet me if you have…
I should qualify that I started writing this script and CSS, based on another experiment of mine, before I saw Aaron Gustafson’s 2005 ALA post Improving Link Display for Print. He uses similar techniques 12½ years ago that I use here, but with different syntax. Because scripting and styling has…

Accessibility standards are enshrined in law the world over, making standards-based semantic and structural mark-up the safest and easiest path. If you do HTML correctly then…
WordCamp Europe has wrapped up in Belgrade. I presented a (not quite) three hour workshop on accessibility, specifically designed to be computer-free. I may have re-used a few slides from my presentation at last year’s WordCamp, but overall this is new material with some WCAG 2.1 references thrown in for…
STOP. This post is very out of date. Much of what this post covers is from a time when support was terrible. Go read these posts instead: Tweaking Text Level Styles, Reprised, 5 April 2025, addresses <del> & <ins>. Disclosure Widgets, 20 May 2020 but updated a bunch since then,…

This year for Global Accessibility Awareness Day (GAAD) I opted to follow my lead from last year and tweet a series of links to articles I have written. This time I limited it to articles I have written since the last GAAD. Just like last year, I am making it…
