padding

NN 4 IE 4 CSS 1

Inherited: No

This is a shortcut attribute that can set the padding widths of up to four edges of an element with one statement. Padding is space that extends around the content box of an element up to but not including any border that may be specified for the element. Padding picks up the background image or color of its element. As you add padding to an element, you increase the size of the visible rectangle of the element without affecting the content block size. You may supply one to four space-delimited padding values. The number of values determines which sides receive the assigned padding.
