Edit File: Filter.ExtractStyleBlocks.Scope.txt
Filter.ExtractStyleBlocks.Scope TYPE: string/null VERSION: 3.0.0 DEFAULT: NULL ALIASES: Filter.ExtractStyleBlocksScope, FilterParam.ExtractStyleBlocksScope --DESCRIPTION-- <p> If you would like users to be able to define external stylesheets, but only allow them to specify CSS declarations for a specific node and prevent them from fiddling with other elements, use this directive. It accepts any valid CSS selector, and will prepend this to any CSS declaration extracted from the document. For example, if this directive is set to <code>#user-content</code> and a user uses the selector <code>a:hover</code>, the final selector will be <code>#user-content a:hover</code>. </p> <p> The comma shorthand may be used; consider the above example, with <code>#user-content, #user-content2</code>, the final selector will be <code>#user-content a:hover, #user-content2 a:hover</code>. </p> <p> <strong>Warning:</strong> It is possible for users to bypass this measure using a naughty + selector. This is a bug in CSS Tidy 1.3, not HTML Purifier, and I am working to get it fixed. Until then, HTML Purifier performs a basic check to prevent this. </p> --# vim: et sw=4 sts=4
