Brings back the good old HTML <blink> tag.

blink.fallback.js

/*global jQuery: false, setInterval: false*/
(function ($) {
    "use strict";
    setInterval(function () {
        $('blink').each(function () {
            $(this).css('visibility', ($(this).css('visibility') === 'hidden' ? 'visible' : 'hidden'));
        });
    }, 250);
}(jQuery));
