title: compress mark-up
body: <p><em>More a theoretical question.</em> </p>
  
  <p>We compress/minify css &amp; js, but has anyone ever thought or tried to compress mark-up?</p>
  
  <p><strong>Q:</strong> Benefits (Pro/Contra) of mark-up compression, possible tools and scripts.</p>
  
  <p>As it's hard to have a <em>solution</em> for this Q, I'll take the most detailed answer.</p>
  
  <p>Thanks!</p>
