Another (possibly dumb) newbie question..
I am using a background image in my header. When using a fixed px size, the image gets cropped (at lower res.) or looks too small (at higher res.) If I use 'em' to size the image it still gets cropped (at lower res.) but "tiles" (at higher res.)
Is there a way to make the image size change based on the reader's resolution setting? If so, can I tie the size of the header anchor text to the image size so they look the same relative to each other at different resolutions?
