Question: I want adding background image with css but it did not work.Browser show me a blank page.

my application.css

```
home-body {
    background-image: url('/home.jpg') no-repeat center center fixed;

    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
     background-size: cover;

}

```

file home.jpg located in a directory /public/home.jpg.

How fix?

Answer: 
If you are using an external CSS file... make sure to link the image file relative to the CSS file. For instance

`-ROOT
 -css
 -file.css
 -background.jpg
 -index.html`

you would need: 

`background("../background.jpg");`

because ".." takes you up one directory :)
```
body {
    background-image: url('img-url');
    background-size: cover;
    background-repeat:no-repeat

}

```
