It’s none. Clarification Let me clarify: don’t set a base font size. body { /* font-size: yeah, no */ } Got a linter or code checker or boss-man hassling you that you need to set something? Ok, use something like this: body { font-size: 100%; } Because This approach has…
Yes, that is the bear from Jakob’s clearly spurious alternative text example and yes, that is The Fonz after jumping the shark. If you have been following the saga of Jakob Nielsen, there a few quotes I could use here: Battle not with monsters, lest ye become a monster (Nietzsche).…
A rambling collection of thoughts from reading through the WebAIM Screen Reader User Survey #10 Results. Most of this was in a Masto thread, but I opted to post it here so I can laugh at myself later. Disability This opening nugget is important for understanding some of my commentary:…
Just another usability and accessibility pro telling authors not to do the thing they continue to do. It’s Ok to Disable Buttons There are plenty of cases where you want to disable a button until a user takes a conscious action to enable it, such as when launching nuclear missiles.…
There are plenty of use cases for embedding third-party content on a site, as well as local content that may not be in HTML. Perhaps you gave a talk and want to share your slides. Sometimes you want to reference a video that exists only on YouTube. Maybe you have…

The native HTML <select> is renowned for its styling limitations. Even with control over the closed state and trigger appearance, the options themselves are still defined primarily by the browser and the OS. While I think this is generally fine (preferred, even), the <selectlist> (nee <selectmenu>) hopes to change that.…
TL;DR: When deleting something you should generally move focus to the prior equivalent control or its grouping container. Why This Is a Thing Plenty of user interfaces let users delete things that are on the screen. It may be an extra address, a calendar item, a message (the same as…
I made a tutorial for styling links and buttons, something which many developers have struggled with (resulting in links used as buttons and buttons used as links). I have embedded it on this page, but if you are coming in with your RSS reader you can visit the tutorial directly…
