Blink tag had never been official HTML tag and it is deprecated now. In fact none of the modern browsers supports blink tag and is not working anymore. In order to find a replacement for blink tag, I was searching around an hour on the net to find proper and robust solution. I have tried few approaches but none of them worked. Finally, I found this JQuery plugin which seems robust and easy to integrate.
Basically the idea of implementing is simple. It utilizes one timer to change the font color or background that is all.
In order to use JQuery plugin, you just download the package from this link and follow the instruction accordingly.
Following is a simple example,
<script type="text/javascript">
$(document).ready(function() {
$('.blink').blink();
});
</ script>
<html>
<body>
<p class="blink" color="red">
This is some text!
</p>
</body>
</html>
