title: How to have navigation bar changes sync across webpages
body: <p>If I am making a website, what is the fastest way to put new pages onto the navigation bar, and be seen from every page. Each time a new page is created, the navigation bar is updated, and then I have to go copy and paste the new code onto every single page's code in my site (I think.) I have just now completed the homepage, so it isn't a problem yet, but I don't want to continue until I have this problem straightened out so I don't end up in trouble later. Is there some way to put the navigation bar's code onto a different HTML file and then link the pages to it so that they all stay synced up? Sorry if that is confusing, but please help me. Thank you so much, I am pretty new to HTML and CSS, but I am willing to learn whatever is required to optimize this.</p>
  <p><strong>Update:</strong>  I now have this working using the PHP command:</p>
  <p><code>&lt;?php include 'PHP/nav_bar_code.php'; ?&gt;</code></p>
