Hi,

I asked this question on stackoverflow:
http://stackoverflow.com/questions/9452615/emacs-is-there-a-clear-example-of-multi-line-fontlocking

Can anyone point me to an example of how to use the features described in
the manual?

Which feature?  There are various.

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.

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

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.
