Missing Syntax-Highlighter

Hello. In a PHP-HTML-Template the Highligt working with DIV SPAN HEADER NAV FOOTER TABLE TR TD .... but not with:

* HEAD
* TITLE
* BODY
* MAIN
* H1
* COLGROUP
* ASIDE
* .....

Is this a bug or only not supported?

I don't understand what do you mean for "doesn't work".
I guess you mean pair tags highlight. Some tags has no sence to highlight - e.g. body, head e.t.c., cause are too log from themselves and there is only one occurence in whole document.

Sorry, I mean "pair tags highlight".
