I am making media query for mobile website and i am trying to set background to image:

```
body {
background: url("../images/back1.jpg") no-repeat center center fixed;
webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}

```

This doesn't work for mobile phones.As i understand i can not use fixed for mobile browsers.My question what other ways are there for making background image without stretching it too much or making it blurry.Thank you for your time
