.wrapper is.footer and .push. The negative margin should always equal to the full height of the footer (including any padding or borders you may add).the same number as the height of
* {
margin: 0;
}
html, body {
height: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -4em;
}
.footer, .push {
height: 4em;
}
Follow this HTML structure. No content can be outside of the .wrapper and .footer
div tags unless it is absolutely positioned with CSS. There should also be no content inside the .push div as it is a hidden element that "pushes" down the footer so it doesn't overlap anything. <html>
<head>
<link rel="stylesheet" href="layout.css" ... />
</head>
<body>
<div class="wrapper">
<p>Your website content here.</p>
<div class="push"></div>
</div>
<div class="footer">
<p>Copyright (c) 2013</p>
</div>
</body>
</html>
