title: jquery: add a style attribute to existing style
body: <p>Add a style attribute to existing style properties</p>
  
  <p>I have a div element:</p>
  
  <pre><code>&lt;div id="permissions" style="clear: both; float: left;"&gt;
  </code></pre>
  
  <p>I want to set border on onsubmit event:</p>
  
  <pre><code>&lt;div id="permissions" style="clear: both; float: left; border: 1px #F00 solid; "&gt;
  </code></pre>
  
  <p>Is there a way to do this: 
  Append new style attribute (border) to existing styles (with out reading existing styles)?</p>
