title: Specify width or height as percentages (%) in jquery options?
body: <p>Quick question: When specifying options for a plugin, is it possible to use percentages (%) for specifying width or height?</p>
  <p>Like in this example:</p>
  <pre><code>var options = $.extend( {
     width: 300,
     height: 200
    }
  </code></pre>
  <p>It doesn't seem to allow for % to be added for specifying width.</p>
