What it the simple difference between menus that are CSS, DHTML or Flash based?

I see that Xara Menu Maker is DHTML base and I've used the ******* DHTML (SourceTec) menu application (I like the ******* application much better). I've seen examples of CSS menus but I've not seen an application that will do all the coding for me and at this time I'm totally confused by the concept. I've also used the SourceTec Flash menu application, it is similar to the ******* DHTML application.

I read the Xara webpage about inserting a Menu Maker menu in a XWD site, can I do the same with a flash menu from the SourceTec Flash menu application?
