Jonathan / Greg, Sorry you are mis-reading my first post: I said: "So I do not think disabling CSS to do away with poor contrast on the focus indicator will make it pass 2.4.7" I raised this question "Poor contrast on focus indicator: SC 2.4.7 failure? " with a hope of hearing from Wayne based on his remarks: "New Fail Case 1 restores 1194.22(d) of the current 508, which has been lost in the 508 Refresh. The author's visual presentation must be removable". I understand para (d) refers to use of user defined style sheets, yet in his test case, I do see a statement that says "2. From the Firefox menu take View > Page Style > No Style". My words "disabling CSS" is used in the above context. Maybe my email was unclear to you because I started another thread after reading Wayne's post. Coming back to my question: Yes, knowledgeable content authors may use CSS to enhance browser's default focus indicator if it is weak. That's good. But consider a case where the default focus indicator is passable. Now if the content author styles the background / foreground colors in a manner that introduces poor contrast and as a result, the focus indicator is no longer clear. It is not the browser's fault but a CSS / author-introduced issue. So is it alright to fail poor contrast on the focus indicator under SC 2.4.7?
