Text Blinking with jQuery

Blinking text can be easily achieved using jQuery. Here's a code snippet that makes any text element with the class "blink" blink indefinitely:

$('.blink').each(function() {
    var elem = $(this);
    setInterval(function() {
        if (elem.css('visibility') == 'hidden') {
            elem.css('visibility', 'visible');
        } else {
            elem.css('visibility', 'hidden');
        }    
    }, 500);
});

To stop the blinking, simply clear the interval associated with the text element:

$('.blink').each(function() {
    var elem = $(this);
    clearInterval(elem.data('blinkInterval'));
});
