 The admin toolbar has been around for years and has been iterated on many
 times. Its [https://core.trac.wordpress.org/browser/trunk/src/wp-
 includes/css/admin-bar.css?rev=44544 CSS file] is now over 1000 lines long
 and weighs 24 KB. Even minified it's still over 20 KB, which I think is
 way too much. Given that the admin bar is loaded most of the time for many
 users, this just slows things down unnecessarily.

 I believe there's an opportunity to clean up the CSS file, get rid of
 legacy selectors targeting things like IE 7 and IE 8, and perhaps even
 make it DRY by leveraging Sass.

 It should be possible to reduce the size of the admin bar CSS without
 reducing functionality or usability.
