Hi. My bottom div refuses to stretch all the way to the left. It's just in the bottom of the body tag, and neither that nor the html tag has no particular styling (except for a stretched background).

Ideas?

P.s! I know the "No copyright infringement intended" is useless.

Answer 1

The body tag has a small default margin - you can unset it with

body { margin: 0 }

Answer 2

.bottom-bar { left: 0; right: 0;}
