title: Magento: adding css to a theme
body: <p>I've picked up the task to modify a magento theme and I am already having huge headaches.</p>
  
  <p>So, I'm simply trying to add a css to page.xml. The css gets included just fine, however, the base URL is off.
  My theme is rwd/default.</p>

  <p>What might be happening?</p>
