title: Tool to parse and compare two CSS stylesheets
body: <p>Does anyone know of a good tool that can parse and compare two CSS stylesheets in order to find which selectors have different styles?</p>
  
  <p>I cannot use a standard diff-like tool because the two CSS files have very different layout. I need a tool that can parse and understand the CSS, then look for selectors that actually have different styles in the two stylesheets.</p>
  
  <p>The only tool I've found is the <a href="http://www.alanhart.co.uk/archives/2010/12/15/compare-css-stylesheet-tool/">CSS Comparer from Alan Hart</a>, however it gets confused when there are styles that apply to multiple selectors.</p>
