title: Are there compilers for HTML/CSS?
body: <p>Many people today use Google Closure Compiler to actually "compile" their JavaScript code. The advanced mode enables it to rewrite JS to better, faster and smaller JS-code that functions the same way as the original input.</p>
  
  <p>Are there any good compilers out there for HTML/CSS? It could for example compress the CSS classes like a JS-compresser does. It could remove any divs (display: none;) that no JavaScript actually displays (display: block;). It could remove whitespaces. It could combine small images into sprites. It could combine files that are included on all pages into one file.</p>
  
  <p>The list just goes on and on. Do you know about any good tools for this job? (Even if it only can compress CSS classes etc.)</p>
