title: Set Flex container layout padding with CSS
body: <p>Is there any way to use Flex CSS to set the padding on this BorderContainer?</p>
  
  <pre><code>&lt;s:BorderContainer width="100%" height="100%"&gt;
     &lt;s:layout&gt;
        &lt;s:VerticalLayout /&gt;
     &lt;/s:layout&gt;
  
     &lt;s:Label text="asdfasdf" /&gt;
  &lt;/s:BorderContainer&gt;
  </code></pre>
  
  <p>I'm trying to avoid adding an extra unnecessary VGroup. Setting the padding with CSS has no effect. (I'm guessing since paddingLeft isn't a defined style on BorderContainer.)</p>
  
  <pre><code>s|BorderContainer {
     paddingLeft: 10;
  }
  </code></pre>
  
  <p>Is there any way to modify properties of the layout with CSS? I don't want to have to hard code padding in a ton of places.</p>
