Description

The padding-bottom property sets the padding to the bottom side of an element using the value specified.

Padding is the area that’s sandwiched between an element’s borders and its content. Any background image or background color that’s applied to the element will extend across the padding area. Refer to The CSS Box Model for an in-depth discussion of how padding is accommodated within the CSS box model.

When vertical padding (padding-top and padding-bottom) is used on an inline, non-replaced element, it can cause the overlapping of elements above and below that element in cases where the padding causes the element in question to exceed the line height. See Inline Formatting for more information.

Value

The property takes a CSS length (px, pt, em, and so on) or a percentage of the width of the element’s containing block. Note that even for top and bottom padding the percentage value will refer to the width of the containing block. Negative length values are not allowed.

In CSS2.1, if the containing block’s width depends on an element with percentage padding, the resulting layout is undefined.

Compatibility

Internet Explorer versions up to and including 5.5 (and IE6 and IE7 when in quirks mode) incorrectly apply padding inside the stated width, thus reducing the space available for content—see The Internet Explorer 5 Box Model.

Internet Explorer up to and including version 6 will often need a position:relative; declaration added to inline elements in order to show the full amount of vertical padding.

Internet Explorer for Windows versions up to and including 7 don’t support the value inherit.
