Use background-size: cover for background images
Use background-size: cover for background images

The background image was previously cover-sized, but this is no longer
the case. cdccd78c650493c6f488217545933e03a2bb0235 introduced multiple
background images, and in the process removed `background-size: cover`.
This commit restores cover sizing.
