Hey Guys.

im still a beginner in css, and i have 2 websites and 1 is a major one, what i designed etc, and i want to know if there is a way of if i change the nav bar in one page, it will change in every other page on the website?

Lee?

Use css for style your documents..That’s all

Yes, but how do i do that?

It depends on what you want to do with your menu. If your site is build using table tags for layout it will be realy hard to change it.
If you are already using div tags than like I said up top you will need to tell us what you want to do with your menu.
