Compares the outerHeight (height including borders and padding, if any) of all DOM elements with the class name provided as argument, then takes the height of the tallest element and applies it to the others

eqHeight.js

function eqHeight(className) {
	var elements = $("." + className),
	    targetHeight = 0;
	elements.each(function(i){
		if ($(this).outerHeight() > targetHeight) { 
		  targetHeight = $(this).outerHeight(); 
		}
	});
	elements.css({'min-height': targetHeight});
}
