the line before the  line is the last line you need to copy, and ye, the first three lines are unneeded, and you'll need to change the hardcoded list for the current usernames.

Also the JS is only needed if you're wanting to apply it to certain users (in clash of clans' case, certain usergroups), as the global masterhead doesn't have a username in it, so they use JS to add a class to use, but you don't need that if you're just wanting to apply the css to everyone.
