Which feature? There are various.

This section of the manual: http://www.gnu.org/software/emacs/manual/html_node/elisp/Multiline-Font-Lock.html lacks an example that ties it all together, IMO.

Most of the "multiline font locking" features are aimed at solving the
situation were a single font-lock rule can match a chunk of text that
spans several lines (e.g. putting a bold font on text within
"\textbf{...}").

For your case (of highlighting the CSS or Javascript part of an HTML
buffer), I think that a "multi-major-mode" approach is more promising,
tho this is an even harder problem to solve than mere multiline
font locking.

I'm sorry. I realize now that my question was unclear. I don't want mode specific highlighting within javascript/css chunks. I only want to see that the chunks are there by applying a face with a slightly different background. So this is simply a problem of multiline font-locking.
