Hi,

Is there any new standard in creating icons to show a link or button
is temporarily non-functional, and meets the color contrast
requirement? Typically I would change the icon to gray-scale.

On the sites I work on, I noticed several of these no longer meet the
contrast requirement.

Thanks,

Nancy Johnson

Note that, strictly speaking, inactive controls don't need to meet any
contrast requirements according to the exceptions on 1.4.3:

"Incidental: Text or images of text that are part of an inactive user
interface component, that are pure decoration, that are not visible to
anyone, or that are part of a picture that contains significant other
visual content, have no contrast requirement."

However, it's of course still good if you can achieve sufficient
contrast, while still making them noticeably different from active
controls (otherwise you have a whole other set of problems where users
can't tell active/inactive apart).

Also worth noting that the browser will generally change the contrast
automatically when a `disabled` attribute is applied to an input, like so:

Swap the image for one with a big "X" on it? Circle-slash?

Hi,

Is there any new standard in creating icons to show a link or button is temporarily non-functional, and meets the color contrast requirement? Typically I would change the icon to gray-scale.

On the sites I work on, I noticed several of these no longer meet the contrast requirement.

Thanks,
