Styles Reduce amount of duplicate CSS
 

I admit that I have not dug that deep into the CSS files* but was curious if this would streamline the amount of some CSS (if it is duplicated).

One example:
-moz-box-shadow:
-webkit-box-shadow

It seems there are 6 separate CSS files that use that particular class. I understand that some areas use different values such as -2px 2px 2px #c8c8c8;.

I was just not sure if there was a way to include all of the dropshadow (or any other commonly used CSS) values in the main CSS template if indeed there are duplicate uses.
Basically just use one generic container to wrap those areas in.
