float
This property influences the horizontal alignment of an element, making it "float" toward the left or right margin of its containing element. Possible values are left, right, and none. Floated regions act much like <img> tags that have been aligned left or right with respect to text.
Examples
#myimage {float: left;}
#pullquote {border-style: double; border-width: 5px;
background-color: yellow; float: right;}
