How do you customize a Major Mode?

How do you customize a Major Mode?

[Robert Jeffrey Miesen]

Hi all.

    I would like to customize how a couple of major mode work (such as CSS 
mode and HTML mode (NOT "HTML helper" mode). How would one go about doing 
such a thing? Also, how would one set the default major mode for a certain 
class of files?

    Thanks in advance.

It depends on what changes you need to do. A general answer could be
"Open html-mod.el and change it", but I won't be that mean... :) Some
people just want to change the "syntax hilighting" (font lock in Emacs
lingua), some want to change the behavior of some function. Maybe if
you describe in more detail what you want to change, people can make
suggestions?

This is how I add the sql, ins, cre and upg file extensions to use
sql-mode:

(setq auto-mode-alist 
 (cons '("\\.\\(sql\\|ins\\|cre\\|upg\\)$" . sql-mode) auto-mode-alist))
