title: Append many classes to style in jquery
body: <p>I have a code that allows to add style with class to head section:</p>
  
  <pre><code>$("&lt;style type='text/css'&gt; .redbold{ color:#f00; font-weight:bold;} &lt;/style&gt;").appendTo("head");
  </code></pre>
  
  <p>If I call this code elsewhere, a new style section is created each time and it looks like this :</p>
  
  <pre><code>&lt;style type="text/css"&gt; .redbold{ color:#f00; font-weight:bold;} &lt;/style&gt;
  &lt;style type="text/css"&gt; .newclass{ color:black;} &lt;/style&gt;
  </code></pre>
  
  <p>Is this possible to add a new class many times to the style section and do not create new ones each time? Thanks for help</p>
