It goes most of the way down, then repeats

Your original code: http://jsfiddle.net/ecKR4/7/

If you want the gradient to stretch the entire height of the page:

html {
    min-height: 100%
}

With little content: http://jsfiddle.net/ecKR4/1/
With lots of content: http://jsfiddle.net/ecKR4/2/

If you want the gradient to be fixed and as high as the viewport:

html {
    height: 100%
}
body {
    background-attachment: fixed
}

If you want the gradient to be as high as the viewport, and then the background colour:

html {
    height: 100%
}
body {
    background-repeat: no-repeat;
    background-color: #669966; /* ending colour of gradient */
}
