A jQuery plugin for that equalises the height of html elements.
You can download the latest version from here:
https://github.com/edwardcasbon/jquery.equalise
To use in your own page, place the jquery.equalise.js file where your web page can load it, and copy the example below.
$(".columns").equalise();
// Note that to equalise different sets of columns you'll need to call equalise multiple times. For example:
$(".columnGroup1").equalise();
$(".columnGroup2").equalise();
