This is the content div, which is inside the container. It is first in the source. It contains some sentences here, just to make it a bit bigger and demonstrate better how it works. As you can see, it stretches between both menus, no matter how you resize your browser window. As you can also see, this layout looks extremely ugly like this; in a real case you would put in some fonts, nicer colors that don't clash as much, some pretty pictures, and paddings.
