When the indicator is a border-box, I'll measure it's contrast against the background to see if it meets WCAG requirements. If the item itself just changes color, I'd make sure that both the focus and unfocused colors have sufficient contrast to background, but I don't compare them to one another.

Subject: [WebAIM] Does button:hover have contrast requirements?

Hello everyone,


I've been searching but with limited time, it's been difficult to find this answer.

Is there a requirement (or best practice) that the hover/focus state of a button (not text link) have some measurable, distinct contrast from its default state?


I know that a button's hover/focus state should look distinctly different than its default state, but is there a numerical requirement that I need to measure, as there is with text color vs background color?


thanks!

Mike
