CSS Basics Tutorial: Clear Floats

CSS has two functions for clearing floats:

(1) You can surround elements to "visually" wrap floating elements

(2) Other elements under clearing will return to the default layout.

Note:

If there is floating, there must be clearing.

If the surrounding element has a specified height, then the clearing function does not need to be used.
