XF 1.5 Header changes

[NickM22]

Is there a simple way to change a header? In this photo http://prntscr.com/ei4elu Can I make the header (Red Square) transparent so its just the site logo? Over on the right (blue square) is it possible to keep a small square under it?

well you could make the header a particular width and center it fits just in the container with the rest
you could also maybe just make it transparent using background-color: rgba (0,0,0,0.5); which is a opaque 50% black
