I’ve been working on my first ever fully fledged web project to try and learn php, and after copying and pasting my top navbar into the 15-ish pages that I have and the styling for it into the 15ish css files that I have, something just clicked and I realized that theoretically, couldn’t I just copy the code for it into a navbar.php file and include that into every page I need it in? Does it also copy the styling? How does it work exactly
