Equalizer is a MooTools plugin which analyzes a given set of elements and equalizers their height, taking into account the box model additions.
Equalizer can be initialized at any time, but will most likely be initialized at DOMReady. There are no required arguments -- only options.
#JS
/* create instance */
var equalizer = new Equalizer('.column');
/* equalize heights */
equalizer.equalize('height');
/* equalize widths */
equalizer.equalize('width');
