Different bg color on the sides and add lines

Look at the picture. I want to have a grey color on the side of my store, and also a line on each side. Does anyone know if there is an easy way to do this on the default template? version 1.4.9.1

#container { There are a few ways to add lines. A simple example is to add:

#container {
