Things to Do Before Asking “Is This Accessible?”

It is not uncommon for someone to message, call, email, or carrier pigeon me to ask if something is accessible. They almost invariably want a “yes” or “no.” However, I need to understand what the heck they mean and what the other-heck prompted them to ask. Yes, I would be…

AT Is More Than Screen Readers

A screen reader is a single element of the overall set of assistive technologies. In practice, however, each is often used as a metonym for the other. Well, hello there. It’s nice to see you. If you’re here because I sent you the link, it’s nothing personal. You’re a lovely…

Don’t Use Web•dev for Accessibility Info

Web.dev is a site from Google Chrome developer relations that provides content both to evangelize Chrome and to more broadly support the web platform. Rachel Andrew’s monthly “new to the platform” posts are effectively required reading to try to stay abreast of the browser support landscape. However, the accessibility content…

Feedback on a Pagination Pattern

Remy Sharp asked on the Mastodon about pagination as he found it in the W3C Design System: <nav aria-label=”pagination” class=”l-cluster pagination”> <ul class=”pagination__list”> <li><a href=”path/to/page”>Previous <span class=”visuallyhidden”>page</span></a></li> <li><a class=”pagination__list__first” href=”path/to/page”><span class=”visuallyhidden”>page</span> 1<span class=”visuallyhidden”> (first page)</span></a></li> <li><a class=”ellipsis”>…</a></li> <li><a href=”path/to/page”><span class=”visuallyhidden”>page</span> 6</a></li> <li><a href=”path/to/page”><span class=”visuallyhidden”>page</span> 7</a></li> <li><a href=”#” aria-label=”page 8″ aria-current=”page”>8</a></li>…

YouTube and Vimeo Web Component

If you want something done right, post it wrong. In the long history of the innertubes, if you ask for help with code you typically won’t get much of a response. But if you post code and assert it is ideal and perfect and an immutable reflection of your pristine…

Maybe Don’t Name That Landmark

TL;DR: You probably don’t need to name that landmark. The Ngong Ping Village tourist trap on Hong Kong’s Lantau Island. All the pricey tourist spots have visible named landmarks on the map, but the ones people generally care about (bathrooms, food, that lovely tea house) are not. The accompanying tactile…

A Brief Note on Highlighted Text

TL;DR: If you plan to style text highlighted by the browser, you must give it sufficient contrast — 3:1 for the highlight block against its background and (probably) 4.5:1 for the text within that highlighted block against that background. CSS Context CSS provides methods to style the highlights that browsers…

Long Alt

TL;DR: Keep your image alternative text brief, devoid of special characters, empty of URLs, and ideally in one language. Here We Go Sometimes you can have too much alternative text, particularly for an <img>. I don’t mean there is a limit to what is allowed, I mean there is a…
