Feature Request: Customize login div background and fonts size/family/color

[Hexcz]

Hello, thanks for the great theme you made (and it have portuguese language differently from others haha), i really appreciated it, but i was wondering if it would be possible to, instead of putting all css attributes on javascript, could you use a actual .css file? So would be easier to some peoples to identify elements and customize on their own liking (for example, i changed login div background, fonts, clock size and font), or maybe make these changes available on settings menu. Thanks a lot again!
