Example
In most cases you want to define several border properties (border-width, border-style and border-color) for all sides of an element.
Instead of writing:
border-width: 1px;
border-style: solid;
border-color: #000;
You can simply write:
border: 1px solid #000;
These shorthands are also available for every side of an element:
border-top, border-left, border-right and border-bottom. So you can do:
border-top: 2px double #aaaaaa;
