RE: code samples for extended description

Further to Daniel’s questions, we have talked about a theoretical media query and user settings to show/hide extended descriptions, but we have not actually talked about whether this is an attribute of ARIA, HTML, or CSS. Is this something the user can toggle? Is this built into the browser chrome?

Whether the additional text would annoy or disrupt people, of course, depends on context. But, if the text gets in designers’ way (or is perceived to), no one will use this solution, so I don’t think it’s a good starting point.

Subject: Re: code samples for extended description


Hello Jason, in the suggested usage of a Media Query, would a CSS selector be used to match all available extended descriptions in the document? If so, then it would make sense to enable content discovery via a well-defined "type" or "role" for the details element (see my previous comment regarding text in the summary element). Daniel

Yes, I think the people who make the effort to use the ALT attribute, then to include a detailed description, are exactly the authors who are most likely to place appropriate text in the SUMMARY element.

This depends on whether the media query becomes available, as has been proposed, for authors to hide the SUMMARY/DETAILS elements from people who do not elect to view extended descriptions.

Finding out to what extent people are in fact annoyed by such additional text would be worthy of an empirical investigation.
