SmartCSS ™ software is mainly based on

the CSS box model. The CSS box model represents every element on a web page

which contains four components:

- The element.
- The padding around the element.
- The border around the padding.
- The margin around the border.

The CSS padding properties define the space between the element border and

the border. Negative values are not allowed. The top, right, bottom, and left

padding can be changed independently using length or % values.

padding-top
padding-right
padding-bottom
padding-left

SAMPLES:
padding: 10px 10px 10px 10px;

or

padding-top: 10px;
padding-right: 10px;
padding-bottom: 10px;
padding-left: 10px;
