Avoid Read-only Controls

It’s weird to me that after I urged everyone not to disable form controls, a bunch of them decided that making them read-only was somehow better. But here we are. What’s in the box? Photo by Michael Heiss, no edits, CC BY-NC-SA 2.0. HTML The readonly attribute is only allowed…

Brief Note on Disclosures in Fieldsets

TL;DR: Probably don’t use disclosure widgets in fieldsets. If you do it anyway, don’t put the trigger in the <legend>. Context With <details> / <summary>, recent support for the popover attribute, and the never-ending belief that a “clean” page means hiding content, there is a resurgence in stuffing useful content…

Under-Engineered Estimated Reading Time Feature

There are plenty of plug-ins, libraries, and tutorials that will add an “estimated reading time” visual cue to your site. There are also browser extensions for users. Most use JavaScript and CSS to calculate based on word count and viewport position. All require more work on the part of the…

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>…

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…

My Approach to Alt Text

I ran across a survey from Tilburg University on the experiences and perspectives of image describers. It asked what process I follow to write image alternative text, and it occurred to me that I don’t use a checklist or guideline anymore. That may or may not be a good thing,…

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…

Jakob Has Jumped the Shark

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).…
