I would like to create multiple two sticky headers just like in that website: http://www.trendyol.com/Kappa/ButikDetay/8690 When you scroll down, the first header combines with the second sticky element. After that, both of them move down together. How can I do it? Thank for advance support!
Answer
The way this is accomplished is pretty easy. You check the scroll position and if it is below a certain number you display a fixed position element at the top (and hide when the scroll position goes backup).
That being said there is a great plugin that can help: https://github.com/imakewebthings/jquery-waypoints
With demo exactly what you want: http://imakewebthings.com/jquery-waypoints/sticky-elements/
AS an update from one of the comments, http://stickyjs.com might be a more supported library.
