Triggering jquery event when an element appears on screen
<p>I want to show a fade effect as soon as the element appears on screen. There is a lot of content before this element so if I trigger the efect on document.ready, at certain resolutions the vistors wont´t see it.</p>

<p>Is it possible to trigger an event when, after scrolling down, the element becomes visible?
I am almost sure I have seen this effect before, but have no idea how to achieve it.</p>

<p>Thank you!</p>
