CSS padding Property
The padding property is used to create padding space on all the sides of an element’s content.
Padding values are set using lengths or percentages.
Negative values are not valid.
CSS padding property is a shorthand for the following properties:
padding-top
padding-bottom
padding-left
padding-right
We can use the padding property for all sides (top, bottom, left, right).
The padding property may be defined with one, two, three, or four values:
When four values are specified the first value sets the top side, the second sets the right side, the third value sets the bottom side, and the fourth value sets the left side.
When three values are specified, the first one sets the top side, the second one sets the right and left sides, and the third value sets the bottom side.
When two values are specified, the first value sets the top and bottom sides and the second one sets the right and left sides.
If the padding has only one value it is applied to all four values
