how to smaller header

As I recall – all I did was find the header background image and cropped out some of the height – resaved it, and used that instead of the default header background. I think the css and styling already is designed to not repeat the background and that the header block is the same size as the background. Although it’s been I while since I tweaked it – you may need to skim through the css to make certain that the css doesn’t give more space for the header – but start with the background image in the theme.
