Use JS for applying focus & add styling for it

Browse Source 
Adds some extra styles so <fieldset>'s show as
focused when they are.

Also includes replacement of `overflow: hidden` on
sticky elements with a clearfix. hiding overflow
clips the outline and the clearfix can be used for
containing any floats instead. (I'm assuming that's
why it was set here.)
