Why the bright yellow? Doesn't that reduce the contrast? Also, the yellow doesn't really go with the general aesthetics of the site.

Hey @mdo it does reduce the contrast - but that's OK. Users who need the focus rely on screenreaders - it's about saying "Hey" this is where I am on the page. That's the reason I chose yellow here and why other sites do to.

Any suggestions to make it more GitHubby?

Use the same shade of yellow as the emphasis tag perhaps?

@brianjenkins94 that could be a good call - what you think @mdo?

I agree our focus states need improvement, but adding a yellow highlight on focus seems excessive and not all that helpful. Can we start with something simpler?

Also, this is what I see on tab focus to elements in Safari:

Do we want to move further away from browser defaults on more elements? Currently we override focus styles for textareas, inputs, and buttons only.

Closed out - lets look in to this again when we have more time
