CSS Formatter and Optimiser

CleanCSS is a powerful CSS optimizer and formatter. Basically, it takes your CSS code and makes it cleaner and more concise. For optimization CleanCSS is using CSSTidy - an opensource CSS parser and optimiser.

Why optimise

CSS Optimiser reduces the size of CSS file more than 30% depending on various conditions, it causes faster loading pages and lower traffic costs.

How optimization works

• Convert Values of CSS property into shorthand notations,
  e.g margin:1px 1px 1px 1px; becomes margin:1px;
• All unnecessary whitespace is removed
• Comments are removed
• The last semicolon in every block can be removed
• All duplicate properties are merged,
  e.g h1,h2,h3{color:##FF0000}
• colors like “black” or rgb(0,0,0) are converted to #000000 or rather #000 if possible. Some hex-codes are replaced by their color names if they are shorter.
