In any case, I'm touching up our CSS a bit. A few things to note about  
the header:

If we're going to have a fixed image be the header, then our  
measurements for page width should be in pixels.

Otherwise, we need to splice the image into left, tiled, and right  
portions, and float divs left and right within the tiled div.

Why? Change your font size in Firefox to 14pt or 18pt and you'll see.
Though it's a very easy fix. Actually, we could just use the logo and  
search bar graphics as a separate entity and float them.
