CSSClass is a JavaScript microframework which adds the functions .hasClass, .addClass, .removeClass and .toggleClass to the Element prototype.

The usage is easy. Include the script file and just use the functions (they can be chained).

var test = document.getElementById('test');
if (test.hasClass('active'))
	test.addClass('glow');
test.removeClass('active glow').toggleClass('golden');
