This is such a strange issue - I'm trying to add in a responsive background image to a really simple site, and I can see that image flicker on the screen while the page loads, however when the page load is complete the image disappears and I'm left with a white background.

Here's the css:

```
body {
  background: url('#') no-repeat center center fixed; 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

```

Here's the [site](http://www.lesliebruce.com/).
