Make the boxes below. Don't worry about the positions on the page, only the styling of the boxes. If you need a small image for a background, snag one of these:
This box is green with a green, "inset" border. It's 100 pixels wide.
This box has an "outset" border and goes half way across the page. The padding is 10 pixels.
A background-image is used here.
This box has no border and has a "height:" property set to make it long.
This is the last one!
This box is 500x500 pixels wide.
