Definition and Usage
The float
property specifies whether an
element should float to the left, right, or not at all.
Note: Absolutely positioned elements ignore the float
property!
Note: Elements next to a floating element will flow around it. To avoid this, use the
clear property or the clearfix hack (see example
at the bottom of this page).
