0008 <p>
0009   If you would like users to be able to define external stylesheets, but
0010   only allow them to specify CSS declarations for a specific node and
0011   prevent them from fiddling with other elements, use this directive.
0012   It accepts any valid CSS selector, and will prepend this to any
0013   CSS declaration extracted from the document. For example, if this
0014   directive is set to <code>#user-content</code> and a user uses the
0015   selector <code>a:hover</code>, the final selector will be
0016   <code>#user-content a:hover</code>.
0017 </p>
0018 <p>
0019   The comma shorthand may be used; consider the above example, with
0020   <code>#user-content, #user-content2</code>, the final selector will
0021   be <code>#user-content a:hover, #user-content2 a:hover</code>.
0022 </p>
0023 <p>
0024   <strong>Warning:</strong> It is possible for users to bypass this measure
0025   using a naughty + selector. This is a bug in CSS Tidy 1.3, not HTML
0026   Purifier, and I am working to get it fixed. Until then, HTML Purifier
0027   performs a basic check to prevent this.
