Some things are either on or off and, when those things aren’t on (or off), they are invariably off (or on). The concept is so rudimentary that I’ve only complicated it by trying to explain it, yet on/off switches (or toggle buttons) are not all| Inclusive Components
Since the early days of the web, when images could be floated and text would wrap around them, designers have wanted to bring drop caps onto the web. Then we learned how terrible a pattern like atthew is for users, and CSS introduced :first-letter, letting us believe all…| Adrian Roselli

3 January 2025: This post is out of date. Read my post Updated Brief Note on Description List Support for the most recent results of testing. TL;DR: Description list support is generally good (with Safari being the outlier), even if you may not like how it is supported. This post…| Adrian Roselli

I have spent a few years banging on about ensuring scrolling areas on a page are accessible to keyboard-only users. This is partly because the term “keyboard” maps to other input types that we distill to “keyboard” for ease of reference (speech input, sip-and-puff, on-screen keyboards, scanning software, etc.). When…| Adrian Roselli

I believe that people with disabilities often end up as unwilling accessibility testers. Any time a person with a disability interacts with the web, they may be unwittingly performing testing because so many websites are not fully accessible to everyone.

TL;DR: for standard HTML controls and standard ARIA patterns (widgets), you do not need to add instructions for screen readers on how to use them nor what they are. When a screen reader encounters an element on the page that invites interaction beyond reading, it typically provides users with instructions…| Adrian Roselli
If you’re a web developer, or if you develop browsers or assistive technologies (AT), the following screenshot is probably familiar to you.

HTML semantics provide accessibility information about page structure and an element's role, name, and state, helping to convey the nature and purpose of content on web pages. In this post we explore what HTML semantics are, and how they're experienced by people using assistive technologies like screen readers and speech recognition software.| TetraLogical

This document describes how user agents determine the names and descriptions of accessible objects from web content languages. This information is in turn exposed through accessibility APIs so that assistive technologies can identify these objects and present their names or descriptions to users. Documenting the algorithm through which names and descriptions are to be determined promotes interoperable exposure of these properties among different accessibility APIs and helps to ensure that thi...| www.w3.org
