hides in the light An interesting feature of aria-hidden is that it hides stuff from screen reader users, but its effects are hidden from everyone else. Unless you going looking for it and understand what it does, you will have no idea how powerful it is and what a detrimental effect it can have if […]
ARIA is an amazing technology, it allows developers to add meaning to meaningless HTML or override meaning on HTML that is being repurposed and sometimes misused, so that users who rely upon the meaning of HTML, as implemented in browsers, can understand and interact with HTML User Interfaces successfully.

It is frustrating having to rehash this discussion endlessly. I first wrote about placeholder back in 2011, and included a note, later a warning, about its use in […]

This article is republished here with updates as the source article can no longer be updated 🙁 In a 2018 article tables and beers I explained how browsers correctly represent table semantics of simple tables with either a row or column of headers.
