   9   If you would like users to be able to define external stylesheets, but
  10   only allow them to specify CSS declarations for a specific node and
  11   prevent them from fiddling with other elements, use this directive.
  12   It accepts any valid CSS selector, and will prepend this to any
  13   CSS declaration extracted from the document. For example, if this
  14   directive is set to <code>#user-content</code> and a user uses the
  15   selector <code>a:hover</code>, the final selector will be
  16   <code>#user-content a:hover</code>.
  17 </p>
  18 <p>
  19   The comma shorthand may be used; consider the above example, with
  20   <code>#user-content, #user-content2</code>, the final selector will
  21   be <code>#user-content a:hover, #user-content2 a:hover</code>.
  22 </p>

  24   <strong>Warning:</strong> It is possible for users to bypass this measure
  25   using a naughty + selector. This is a bug in CSS Tidy 1.3, not HTML
  26   Purifier, and I am working to get it fixed. Until then, HTML Purifier
  27   performs a basic check to prevent this.
