title: Opacity is showing different shades on different pages
body: <p>I'm using opacity and it seems that it's showing as different shades on the pages I am using it on.</p>
  
  <p>If you take a look here at the PS4 image: <a href="http://chrisbrighton.co.uk" rel="nofollow">http://chrisbrighton.co.uk</a></p>
  
  <p>...and then here at the same image... <a href="http://chrisbrighton.co.uk/Gaming.php" rel="nofollow">http://chrisbrighton.co.uk/Gaming.php</a></p>
  
  <p>You'll see that there are different shades but they are all using the same CSS rules.</p>
  
  <p>Any ideas why this is happening?</p>
  
  <p>Thanks.</p>
