> Thank you for your response, Charles. I believe it's good practice to provide highly visible focus indication anyway even though it's sufficient to rely on the browser. In cases where we cannot, in fact, rely on the browser, that's where subjectivity comes into play. It can become a slippery slope when you start compensating for various defects, hence my question about anyone doing something about it.

Right. For normal HTML text and more-or-less unstyled widgets, I am inclined not to provide anything, but for example in SVG I think it is generally useful to highlight where a user is at in stepping through a diagram - especially as you can't know what their own focus highlight is, and it may vanish against a background or outline a much larger segment of the image.

I've got teams that have also created some really good visual focus indication based on the background color. It can definitely be an improvement when done right.

Yep.

> I do have one gripe about SC 2.4.7 Focus Visible: How do you quantify "highly visible" in reference to an outline? Proper contrast at, say, 4.5 to 1? I speak in reference to the sufficient technique listed at the following link: https://www.w3.org/TR/2016/NOTE-WCAG20-TECHS-20161007/G195

Good question. It's probably worth raising an issue...

cheers
