khronos.css very old - can it be updated?

The khronos.css file is using very outdated CSS. Can we modernize?

Also note that git.io/normalize as shown in the first line of khronos.css should now be https://github.com/necolas/normalize.css and updated.

Start by reviewing khronos.css, particularly its first-line reference to git.io/normalize, and compare it with the current normalize.css at the linked GitHub URL. Done means the outdated CSS has been modernized and the normalize.css reference has been updated, though the issue does not define the broader modernization scope.
