jQuery Waypoints

Hello Experts,

I am trying to do, for the first time, something very simple using the jQuery Waypoints plugin.
I am changing the "header" classes depending on the window scroll offset.
Here is an online example: http://codepen.io/ilan-lavi/pen/scwHb

What happens is when you resize the screen (viewport) the style is gone. I was trying to fix this using the "refresh" method as in the Waypoints documentation but no luck. Please see that page link above and re-size the window.

Any help would be appreciated!

I believe you've got the waypoint on the wrong element.  Given it's the section that's scrolling, not the header, it should be initialised on that:

Hi Rob Jurd, Thank you.

Shouldn't you apply the Waypoints on the element it self? What you are doing here is applying it to an element after the one you want to animate. What if i need to apply the same on the footer, should i then apply it to an element before it?

Yes that's exactly what you'd do because it's the element before it that you would be scrolling.
A little bit counter intuitive isn't it

Rob Jurd Thank you!

The idea of applying the waypoints to an element before/after the element you trigger is indeed working yet in all the examples / tutorials i saw they always applying it directly on the element it self. Anyway if it works then it works :-)
