Padding is used to create space around an element's content, inside of any defined borders.
The CSS padding properties are used to generate space around an element's content, inside of any defined borders.
With CSS, you have full control over the padding. There are properties for setting the padding for each side of an element (top, right, bottom, and left).The padding property may be specified using one, two, three, or four values. Each value is a length or a percentage. Negative values are invalid.
