Thoughts on callout semantics

Noted by on their . Last updated . Changelog

Interesting proposal! Some thoughts:

  • I’d suggest looking into the doc-notice, doc-tip, and doc-example DPUB-ARIA roles. I’m a big fan of DPUB-ARIA and I do not think it is used enough. I believe Google’s Talkback has the most robust support for it put of any AT I’m familiar with.

  • I’m not convinced that a cot element is necessary. I think a heading with aria-labelledby would work better as a way to name a callout, and an attribute (or DPUB-ARIA role) could better specify the type of callout.

Funnily enough, I’m thinking about my own proposal for a spoiler element which also has similar structure to—but different semantics from—the details element.
