title: Using both CSS and setStyle
body: <p>I have an object where I have css stylizing the object.  In my program I would like to change specific elements in the styling such as background color. The problem that I have run into was that when I call setStyle(-fx-background-color:red)  it will override all the styling elements. Even if I just change background color.</p>
  
  <pre><code>#header {
  -fx-background-color: #4d4d4d;
  -fx-border-color:  #545454;
  -fx-border-width: 1px;
  -fx-border-style: solid;
  }
  #header:hover {
  -fx-background-color: #9ACD32;
  }
  </code></pre>
