This is the content div, which is inside the container and the second 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 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 and some prettier and fancier pictures, although this one does have paddings. The column backgrounds in this example look like solid colors, but in fact it's this 779x1 background image which is on the container. In a real layout, your background image would of course look a lot better than this.
