How to do something when user scroll until a div?

Is it possible to do an action if a user see the id="content" ?

Answer 1

I answered a similar questions at horizontal scroll, detecting scroll position relative to anchors

See working example http://jsfiddle.net/Vy33z/4/

You can also use a plugin if you are not too familiar with jQuery. The Appear plugin is great and easy to use. All you need to do is

$('#mydiv').appear(function() {
  alert('Your div is in view');
});
