How do I fill the header with the background color without specifying the pixel height?
I was playing with responsive design and wanted to know how to fill the title with the background color without defining the pixel height, which I used to do but is not responsive.
My demo is here and you can see that I was trying to fill the title with yellow
The problem is your div content is all floating, so it collapses to 0 height. You can simply fix this by placing a container. Depends on what else you want to add.
