Is it possible to have an editable side navbar in an external style sheet?

[djdel002]

Hi,

I have a quick question, hopefully this makes sense. I'm a little new to CSS.
All of my html pages use the same navbar, is there a way with an external style
sheet to control the navbar, in other words edit it and add things when needed
instead of opening each html page and change individually??

Thank you for any help.

CSS contings styles and visual effects.
html contains the content.

If you want to have the same bit of html on every single page but only write the code once, then you should use a Server Side Include or a PHP inlcude.
