The padding-bottom property

The padding-bottom property sets a bottom padding of an element. The property value is any size units.

Syntax

selector {
	padding-bottom: value;
}

Let's make the 30px bottom padding:

<div id="elem">
	some text...
</div>

#elem {
	padding-bottom: 30px;
	width: 300px;
	border: 1px solid black;
	text-align: justify;
}
