 *
 * Note 2: jQuery's CSS selectors don't play well with special characters, that's why you'll notice the use of the
 * filter method. This simply calls a function to test the equality of certain attributes instead of using the
 * typical $('element[name=value]') syntax but achieves the same goal.
