title: How to add a custom css stylesheet to Umbraco Admin
body: <p>Wondering if anyone knows how to add a custom css stylesheet to the admin backend section, without altering the original masterpages/umbraco.aspx.</p>
  
  <p>I have a custom section implemented, so it has it's own section tray icon, and I can add the css to the 'umbracoGui.css', but I'd like to just 'inject' my own css file for any further styles too, knowing that all of the original files are intact.</p>
  
  <p>In summary, say I have customStyle.css, with all of my css in. To add it to the head of the whole of the admin section.</p>
  
  <p>There seems to be a few mentions of skinning, but it seems a bit overkill to me.</p>
  
  <p>Is there a way of creating a class or something, that can register the stylesheet, or something like that?</p>
  
  <p>Thanks for any help!</p>
  
  <p>Cheers,
  Bav</p>
