Make body have 100% of the browser height?

Question

I want to make body have 100% of the browser height. Can I do that using CSS?I tried setting `height: 100%`, but it doesn't work.I want to set a background color for a page to fill the entire browser window, but if the page has little content I get a ugly white bar at the bottom.

body {

height: 100vh;

width: 100vw;

background-color: blue;

}
