Changing body background when hovering over a link

Question

I would like to set up my page so that when the user hovers over a link in a div, the color of the body background is changed, but only while hovering. This is the css

It's not very pretty, but you can use the :before pseudo-element on body

CSS:

body {
    background: #fff;
}

a.change-bg:hover:before {
    content:'';
    position: absolute;
    display: block;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    z-index: -1;
    background-color: #000;
}
