The jQuery plugin below allows you to name an element as a sticky header or footer. You can also set the height, width and background colour. This is similar to those available in Twitter Bootstrap and ZURB Foundation.
First the HTML page:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>jQuery sticky footer</title>
<style>
body
{
font:90%/1.6 sans-serif;
}
section
{
margin-top:6em;
}
</style>
<!-- HTML5 Shim and Respond.js IE8 support of HTML5 elements and media queries -->
<!-- WARNING: Respond.js doesn't work if you view the page via file:// -->
<!--[if lt IE 9]>
<script src="https://oss.maxcdn.com/libs/html5shiv/3.7.0/html5shiv.js"></script>
<script src="https://oss.maxcdn.com/libs/respond.js/1.4.2/respond.min.js"></script>
<![endif]-->
</head>
<body>
<header>
<h1>Hello, world!</h1>
</header>
<section>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec ac pretium velit. Morbi scelerisque vel risus sed ullamcorper. Integer nec dui vel magna malesuada tempus. Vivamus dictum elit sem, at mattis leo volutpat in. Phasellus felis metus, dapibus semper nisi non, sagittis lacinia erat. Fusce in diam et velit commodo rutrum in in dui. Sed imperdiet est non dui molestie consequat. Duis ac ipsum in purus tempor dictum. Curabitur ac neque sed sem semper congue. Pellentesque enim enim, congue sed consequat et, lobortis id tortor. Cras a faucibus sem. Mauris sed enim quam. Aenean sollicitudin posuere mauris. Curabitur sollicitudin orci orci, a sagittis neque feugiat nec.</p>
</section>
<footer>
<p>Hello footer world!</p>
</footer>
<!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="sticky.plugin.js"></script>
<script>
/* Example parameters
$('header').sticky(
{
position:'top',
height:'10em',
width:'50%',
background:'red'
});
*/
$('header').sticky(
{
position:'top'
});
$('footer').sticky(
{
position:'bottom'
});
</script>
</body>
</html>
Now the jQuery plugin, sticky.plugin.js
(function($)
{
$.fn.extend(
{
sticky:function(options)
{
var defaults =
{
position:'bottom',
height:'4em',
width:'100%',
background:'white'
}
var options = $.extend(defaults, options);
return this.each(function()
{
var o = options;
$(this).css('position','fixed').css('_position','absolute').css(o.position,0).css('background',o.background);
$(this).height(o.height);
$(this).width(o.width);
$(this).css('z-index', 9999);
});
}
});
})(jQuery);
