Interesante técnica para simular el uso de “frames” con CSS, sin usarlos como los conocemos.

¿Cómo funciona?

The document

consists of three main blocks: headerwrap, middlewrap and footerwrap. headerwrap and footerwrap have fixed positions; headerwrap at the top and footerwrap at the bottom of the viewport. middlewrap has

padding-top and padding-bottom to match the heights of headerwrap and footerwrap.

To center the content horizontally, the contents of each of the main blocks has its left and

right margins set to auto.
