title: CSS parallax scrolling with background image moving
body: <p>Here is what my parallax scrolling currently looks like:</p>
  
  <p><a href="http://www.w3schools.com/howto/tryhow_css_parallax_demo.htm" rel="nofollow noreferrer">w3schools.com</a></p>
  
  <p>I have this:</p>
  
  <pre><code>background-image:url("http://google.com");
  background-attachment: fixed;
  </code></pre>
  
  <p>i want this but i don't want to use the "materialize css" stuff: <a href="http://materializecss.com/parallax.html" rel="nofollow noreferrer">materializecss.com</a></p>
  
  <p>where the <code>background-image</code> moves a little while you scroll up or down the page.</p>
