title: How To Set CSS Classes On HTML Tags Which Are Included In The Page With PHP Include's
body: <p>I'm building a website which uses a lot of repeated styles and HTML tags, such as the header, the navigation bar at the top, and the footer at the very bottom. Instead of typing all of that repeated code in again and again, I'd like to use PHP include statements to include everything that I need.</p>
  
  <p>While that's all well and good, this poses a problem with my navigation bar. I use a CSS class attached to the navigation link to let the user know what page they're on (using a different background color). On each page, I manually specify which link gets that special class. If I were to simply include that content via a PHP include statement, I couldn't manually specify the class.</p>
  
  <p>My question is: how would I be able to do that? Either by using a separate PHP script to find out which page the user is on, and then specify the class to style the link appropriately, or by using JavaScript to do the same thing? Or maybe there's something else that I'm missing? Who knows! And as such, I ask!</p>
