Is it possible to add css drop down menu tutorial on all pages?

Q: Is there anyway I can build one code for the body and use it on several pages as an include page? I would like to be able to change the code and it changes on all pages.

A: CSS3Menu doesn't provide possibility to insert menus on multiple pages.
You can use a server-side script (php, asp, vb, etc.) to generate html pages from templates on your server. Or you can use any CMS/web editor (Dreamweaver, Frontpage, Joomla, etc.) that allows to create templates.
