Cross browser fix + more responsive

* UI is far more consistent across Chrome, Safari, Firefox, and IE
(only tested on the latest versions of each).
* Responsive improvement: BG number, clock, etc now collapse together
neater on small screens.
* Collapsing the toolbar now increases the font size of BG, clock, etc!
:)
