Setting up Custom Background [closed]

Use this css style to make your background cover the entire page:

body {
    background-image: url('IMAGE URL');
    background-repeat: repeat;
    width:100%
    overflow:hidden;
    float:left
}

Now, style your content’s background:

.grey {
    background-color: #e6e6e6;
    display: block;
    float:left;
    overflow:hidden;
    width:500px // You can also set as 100%
}

Not that you should either set a width for your elements, or float it to the left to be able to set it’s background.
