Thanks! Actually my hope is to change the appearance very little, but to put the navlinks and page navigation and the jumplink (jumps down the page to the modules, for use on mobile) into the header in the form of icons, so that they all show up at the top on mobile without eating too much space.

Although I've also been thinking I want to make a light version of my color scheme and add a link to the page that would switch the style, for my own use. Fingers crossed for getting the header right first though.
