Automated accessibility testing tools cannot test 100% of WCAG. This position is not controversial. Other than overlay vendors, no automated tool maker makes that claim. This is partly because WCAG is targeted at humans, not code, and so nuance and context apply. Free automated accessibility testing tools may have even…
As the world’s leading expert on a people-first approach to computer vision, I am dedicated to providing insights that enable designers, developers, and copywriters to create accessible images at the highest possible velocity. A velocity so high, in fact, you can almost hear the point whistling over their head, like…
First, a very important qualifier — this does not represent how Braille display users experience the web. All this post does is show how to enable the Braille display emulators in JAWS, NVDA, and VoiceOver. This can be handy when testing issues reported by users and you do not have…
There is a non-zero chance that WCAG Success Criterion 4.1.1 Parsing will go away in WCAG 2.2. This isn’t a problem for users, regardless of the problems it may pose for the WCAG process, ACT rules, automated testing tools, or ossified testing processes. The joke here is using an antique…
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 builds on my 2020 tests when iOS 14 finally added (partial) support for description lists (VoiceOver on iOS 14 Supports Description Lists). The <dl> has existed…
It’s a dice advent calendar. I have no idea how five Platonic Solids and some D10s will carry for 24 days, but I am going to find out. Web developers around the world have for years given a nod to Saturnalia solstice Isaac Newton’s birthday Yule wassailing mummering end of…
TL;DR: Support for aria-readonly is nearly non-existent for the roles I tested. Should you need it, you cannot rely on it. You will be better off revising the pattern where you think you need it. For some background, the aria-readonly property: Indicates that the element is not editable, but is…
Now that it is a market differentiator to talk about accessibility in projects, that’s all many do — talk about it. In a sea of pop-dev noise, “accessibility” can be claimed with little risk someone will challenge it. If someone does, the response is often a fine balance between silence…
“Tires are foundational to all our concept cars! You can tell because we left a wheel well to hold one!” A common refrain I see from companies is a variation of “Accessibility is a core principle!” They will include it in messaging, brag about their team, talk about how great…
I presented this talk for the 2022 installment of WordPress Accessibility Day, a model very much influenced by the ID24 event — 24 hours solid of online talks. I have embedded the video here, though this encompasses six session. The video should be cued up to my session. You can…
The slides for my talk are available as a
I had the pleasure / terror of presenting a table-top RPG presentation at this year’s accessibility Toronto gaming (#a11yTOgaming) event. My 0riginal PowerPoint presentation, which includes my speaker notes / ignored script as well as the videos (79MB). Or grab the much smaller video-free tagged PDF (13.2MB). The background for…
