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…

Brief Note on Dismissing Selects and Listboxen

Native controls can be different from their roled-up ARIA equivalents in a variety of ways. For example, an expanded native HTML <select> on mobile behaves differently when the dismiss gesture is used than when the same gesture is used with an expanded ARIA listbox. Using Android with TalkBack, a down-then-left…

GitHub Contributions Chart

Perhaps a testament to how little I might value GitHub contributions. GitHub profile pages are, to many, the de facto place to quickly judge the value of a developer. The contributions chart is an at-a-glance visual indicator of that value. I disagree completely with the notion of the chart (or…

A Responsive Accessible Table

Painfully slow demonstration of the example table resizing and different media queries kicking in. After writing (again) that it is ok to use tables, and after providing quick examples of responsive tables, I received questions about why I used some of the code I did. I am going to attempt…

Avoid the Hamburger Menu for Desktop Layouts

This is, to some extent, a response to the article at Usability Geek titled Making A Case For The Desktop Hamburger Menu (which I had the Wayback Machine capture because I have learned my lesson). I left a comment on the article, but it motivated me to write something on…

Don’t Disable Zoom

Codepen demos showing a page zoomed and a page that has disabled zoom on mobile. A handy feature of mobile browsers is the ability to zoom into a page with a simple gesture. A less handy feature is the ability to override that. Ultimately this is bad for users. Sadly,…
