Create Blinking text using jQuery and JavaScript

Hello,

I created a blinking text on my web page and it worked.

But when I tried to copy the blinking text to all the web forms but the text is not blinking on the other webforms.

What could have been the issue?

Javascript

<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="http://code.jquery.com/jquery-1.8.3.js"></script>
<script type="text/javascript">
    $(function() {
        blinkeffect('#blink');
    })
    function blinkeffect(selector) {
        $(selector).fadeOut('slow',function() {
            $(this).fadeIn('slow',function() {
                    blinkeffect(this);
            });
        });
    }
</script>

HTML

<label id="blink" runat="server" style="text-align: right;background-color:#01173e;color:#fff;font-size:15pt; margin: 10px;">Free Delivery Nationwide</label>
