title: How do I use @media queries in PHP?
body: <p>I'm trying to add a width-responsive element to a client's page.  The website was made in PHP, which I'm not familiar with.  I believe he's also using Wordpress (which I'm also not familiar with).</p>
  
  <p>The .php pages don't have any head tags to add external or internal css in, and attempting to add a head produced no results.  He did inform me that all his css is loading from a file called "style.css" (though I can't find any actual links to it), but attempts to add css to this file also produced no results on the page.  I was able to style the element using inline css, but apparently there's no way to set up @media queries inline.</p>
  
  <p>As a last ditch effort, I finally got it working using Javascript with window.matchMedia, but it only detects the size when the window is reloaded (this is a second, separate problem I'm having).  I'd still prefer to get it working using css somehow.</p>
