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. The results of my testing here update the tables in that post. One of the primary challenges of using the browsers’ default…

Media Queries in HTML Video

Before you get too far into this post, maybe read Browser Video Players Review. There I wade into the accessibility of the <video> element based on the video players browsers provide. Then maybe read Scott Jehl’s How to Use Responsive HTML Video (…and Audio!). I am leaning on support in…

Obligatory WCAG 2.2 Launch Post

It seems everybody who dabbles in digital accessibility is blogging about WCAG 2.2 now that it finally went live. This is my obligatory post, but I am not promoting it because there is already so much noise and much of the content is regurgitated. If you are not aware, WCAG…

The 411 on 4.1.1
