--DESCRIPTION--

<p>

 

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>

 

23

<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.
