The spec says - #the-hidden-attribute: ]] It is similarly incorrect to use this attribute to hide content just from one presentation — if something is marked hidden, it is hidden from all presentations, including, for instance, screen readers. Elements that are not hidden should not link to or refer to elements that are hidden. For example, it would be incorrect to use the href attribute to link to a section marked with the hidden attribute. If the content is not applicable or relevant, then there is no reason to link to it. It would similarly be incorrect to use the ARIA aria-describedby attribute to refer to descriptions that are themselves hidden. Hiding a section means that it is not applicable or relevant to anyone at the current time, so clearly it cannot be a valid description of content the user can interact with. [[ -- leif halvard silli
