Sidney Paget illustration of Sherlock Holmes from Strand Magazine, December 1892, p.646, but I added papers from his March 1893 (p.281 of Strand Magazine) illustration and then two versions of the W3C logo to the front page. When performing a WCAG evaluation (or review or audit), it’s easy to get…

The 2.1.1 “specific timings” Clause

Web Turns 35, Seems Popular

The world wide web has officially lasted 35 consecutive years, which means it’s catching up to its parent, the Internet, which itself is bearing down on 55. That’s an important distinction. The Internet is not the web; it is the foundation on which the web was born. Prior Years For…

AD Support in HTML Video

This post supplements Browser Video Players Review. There I wade into the de facto accessibility of the <video> element based on the default video players provided by browsers.
