Failing at the first hurdle I am concerned. Not about Large Language Models (LLM)s doing me out of a job, but about the people who make money out of them not making their User Interfaces (UI)s accessible. Not about their ethical use, though there is plenty to be concerned about, but about the accessibility and usability […]
A friend and colleague pondered why ARIA role=presentation and its facsimile role=none is not allowed on focusable elements? The answer is, theses days, purely a function of implementation reality. It don’t work on interactive elements or indeed any focusable elements, regardless of their semantics. When role=none is used on a non-interactive element such as aside, […]

The HTML spec tries hard to give <b> & <strong>, and <i> & <em> distinct and intrinsic meaning beyond the meaning that emerges from their visible default styles (and related aural styles): The i element Represents a span […]

aria-labelledby usage notes
updated August 21st 2023 Like aria-label, aria-labelledby provides the opportunity for a developer to expose a short text string as the accessible name for an element. The mechanism to do so differs. While aria-label accepts a string of text, aria-labelledby accepts 1 or more id values (NOT a STRING OF TEXT). The same opportunity is […]
aria-owns is surprisingly strong magic aria-owns allows developers to restructure the parent-child relationships in the accessibility tree. This means that screen reader users may experience a different semantic structure and meaning to other users when they navigate and interact with content using their screen readers virtual/browse mode. Accessibility Tree Tree of accessible objects that represents […]
Emojis Emojis are derived from Unicode symbols Unicode symbols do not have inbuilt text alternatives. They are exposed in the browser accessibility tree as a text symbol: The text alternatives for Unicode symbols are usually contained within a text file in screen reading software’s program files directory. For example the JAWS 2021 file for (English […]
