title: Linking HTML to deleted CSS file behaves as if the file is still there
body: <p>First things first, I'm fairly new to this and could be making a silly mistake.</p>
  
  <p>I'm running apache2 on my raspberry pi. I had a link in my HTML document to a CSS document with a background picture in it. After some trouble making any changes to the contents displayed, I eventually ended up erasing all the content in CSS document and then deleting it completely. Yet the image still displays. When I comment out the link to the (now removed) CSS document, the image that it was instructing the browser to display disappears. </p>
  
  <p>I tried restarting the system but the "ghost file" is still working.<br>
  I'm using nano for the editing if that means anything.</p>
  
  <p>The HTML-CSS link looks like<br>
  <code>&lt;link href="/css/index.css" type="text/css" rel="stylesheet"&gt;</code><br>
  Running <code>ls</code> while in /var/www/html/css returns nothing.</p>
  
  <p>Please help!</p>
