           Summary: @hidden should override any CSS display properties
           Product: HTML WG

The HTML Accessibility Task Force in discussion on 4 October 2012
http://www.w3.org/2012/10/04-html-a11y-minutes.html#item02 identified that it
was not clear how @hidden relates to CSS display properties. For instance, is
@hidden equal to display:none? What happens if the author changes to
display:block but leaves @hidden set? 

In discussion, the group concluded that the spec should say explicitly that
@hidden trumps all CSS. Regardless of what changes are made to CSS for an
element, all the processing requirements for @hidden elements remain in effect.
For CSS changes to have any impact, the author would have to remove @hidden.

This proposal will probably need to be vetted by the CSS WG. It does appear to
have consensus of the HTML Accessibility Task Force telecon from 4 October 2012
at the time of filing.
