Cascading Style Sheets (CSS) is a style sheet language used to change the style of web pages and user interfaces written in HTML and XHTML.

Resizing of Web Page Elements to Browser size

<div class="outer"></div>

with styles…

.outer {
    width: 100%;
    height: 100%;

CSS fails sometimes when considering browser height due to document vs. window heights. Some JavaScript can help.

<script>
  Webflow.push(function () {
    var fulls = $('.full-page');
    var win = $(window);
    Webflow.resize.on(function () {
      fulls.height(win.height());
    });
  });
</script>

For elements to fill a page, the body of the page has to be the full browser height. To make a vertical element that fills the page, first make the page fill the browser <body>

html {
	height: 100%;
}
body {
	margin: 0;
	padding: 0;
	height: 100%;
}
#content {
	background: #D00;
	border-left: 1px solid #000;
	border-right: 1px solid #000;
	padding: 0 20px 0 20px;
	margin: auto;
	font: 1.5em arial, verdana, sans-serif;
	width: 960px;
	min-height: 100%;
}

Make sure you use #content div "min-height: 100%" instead of "height: 100%" so that if the content of the #content div extends beyond the height of the window, the background will expand as well.
