Positioning in Practice

Using the fixed position also allows you to develop headers or menu bars that are “sticky”. Study the following example for how to create a “sticky header and menu”.

It is standard to wrap your navigation bar elements in the <header> element.

Notice, that when you scroll the below example, the header stays in place. Also notice, that in order to accomplish this look, we have to move the .main-content container down, so that it does not appear behind the header.
