this is my code
<img class="Buble2"
src="http://www.spidycode.com/testing/revibe/images/Bubble-8.png">
<script>
$(document).ready(function(){
$(".Buble2").hide(0).delay(500).fadeIn(3000)
});
</script>
this fade in works perfectly.but I need that to work the animation after the content is in the viewport.how can I do this
