I don't want to make changes in drop down menu in css on all pages.

Q: I'm playing with your CSS3Menu program.
Is it possible to create a Menu and then put a link to it on the web page?
In other words can I make a change to the Menu and have it reflects on all pages or do I have to go to each page to make the changes?

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.
