How can I make the header stand out from my content a little more? The background for the header is currently an off-white color, which makes it hard to differentiate the header from my content (which has a solid white background color). I tried playing around with the colors, but couldn’t find anything appropriate other than off-white, so I thought about using a custom image as a background for the header.
How could I implement this, and what should the dimensions of the image be?
