role=dice for #a11yTOgaming

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…

a11yTO Conf: CSS Display Properties versus HTML Semantics

Update In early July 2022 I re-tested these to see how the results shaped up after nearly two years and at least one promise: It’s Mid-2022 and Browsers (Mostly Safari) Still Break Accessibility via Display Properties If the title is not clear, one browser stands out in failing to address…

Slides: The Role of Design in Accessibility — a11yTO Meet-up

Last night I drove up to Toronto, braving concurrent matches from two of their local sporting clubs, parking in oblivion, navigating a maze of progressive rings of fencing, sneaking into the venue via a propped service door, and presented on the role of design in accessibility. It was a code-light…

Joseph McLarty led with an overview of accessibility as a concept, touching on disabilities and simple testing techniques (see his slides at SlideShare).

What Does X% of Issues Mean?

I ran a highly scientific and well-scoped Twitter poll (yes, sarcasm) to ask a question that has been in the back of my head for some time: When you see a claim that an automated accessibility testing tool finds X% of issues, what do you believe the word ‘issues’ means…

It’s Mid-2022 and Browsers (Mostly Safari) Still Break Accessibility via Display Properties

It was late 2020 when I last tested how browsers use CSS display properties to break the semantics of elements. I had been waiting for Safari to fix how it handles display: contents for four years now, and was excited when the announcement came in June. Then I started testing…

Use Legend and Fieldset

It’s 2022 and people are still afraid to use <fieldset> and <legend>. I understand the layout challenges can be frustrating, but swapping to an ARIA group role will result in a more inaccessible experience.

Under-Engineered Responsive Tables

I have written a bunch about responsive tables. Maybe too much. I keep trying to give developers the information they need to make informed decisions — ARIA attributes, screen reader & browser pairing results, bugs, and so on. I have spread things out over years of posts. I have filed…
