title: Escaping string in less and passing variables
body: <p>By using Less I need to escape a string which  LESS doesn’t recognize.    </p>
  
  <pre><code>filter: ~"progid:DXImageTransform.Microsoft.gradient(startColorstr=#26ffffff, endColorstr=#24ffffff)";
  </code></pre>
  
  <p>At the same time I need to pass two variables startColor and endColor to this string</p>
  
  <pre><code>.get-ARGB(@startColor, @endColor){
      /* ARGB backgrounds for IE 7+8 (black background with 50% transparancy) */
      filter: ~"progid:DXImageTransform.Microsoft.gradient(startColorstr=@startColor, endColorstr=@endColor)";
  }
  </code></pre>
  
  <p>Any ideas how can I do it?</p>
