Enforce shorthand properties

[madhavipuliraju]

When using a rule like the one bellow you should check if it has a shorthand property and if possible use it, it will shrink your file and speedup your page load time and it will even make your CSS more readable and simple.

Ex:

 .foo {
   margin-top: 10px;
   margin-right: 20px;
   margin-bottom: 10px;
   margin-left: 20px;
 }

Should be:

 .foo {
   margin: 10px 20px;
 }
