PHP Help with adding menu to CSS, please

I've d/l'd the Beauty template and it's worked just fine. https://freewebsitetemplates.com/preview/beautysalon/

I have been editing this menu, then copying and pasting the links onto subsequent pages. Then it occurred to me rather belatedly that perhaps I can just add links to the CSS so that the menu is automatically and instantly changed on all pages.

Here's the part of the CSS that I think refers to the menu. I can see the dots that appear in the menu, but there's nowhere for link info.

I've done a lot of webstuff though I'm fairly new to CSS. I'm using front Page to do my editing. Any help is appreciated!

May not be the answer, you could try adding your menu into a single page called "menu.php" or "menu.asp" and only have the table or css div's needed in there.

Then inlcude the file where the menu should go on your page.
That way you edit only one menu and not five or more pages.

All the html and body tags would be out.
