Hi,
I have used blink effect in jquery. It works fine in google chrome browser, but doesnot work on IE8. Here is my code:

$(function() {
    blinkeffect('#txthelpline');
})

$('#txthelpline').fadeIn(2000, function() {
    this.style.removeAttribute('filter');
});
    function blinkeffect(selector) {
        $(selector).fadeOut('slow', function() {
            $(this).fadeIn('slow', function() {
                blinkeffect(this);
            });
        });
    }
