tool to remove repeated css selectors

Question

I have 3 stylesheets that I have copied and pasted all into 1. As such, there are identical/repeated selectors. Is there an effective tool I can use to remove all repeated selectors if the style properties are identical? Another requirement is if the repeated selector exists once within a group of selectors and once as a standalone selector... the program will remove the selector AND properties of the standalone only (not delete the properties of the selector in a group).

I have no clue if this is possible, but have just spent a few hours looking for one with no avail. Anyone know of anything close? Thanks in advance!

Answer 1

Dust-Me Selectors(FF Plug-in) will remove any unnecessary or duplicate CSS Selectors.

Today i found this tool it can merge same selectors.

For example:

p { margin: 0 0 1em}

p { background: #ddd}

p { color: #666}

After compresses using this tool it will be converted to

p{margin:0 0 1em;background:#ddd;color:#666}
