I have a following problem. I have an element in my prototype that is positioned some distance from the. I need for this element to stick to the top of the device screen when I scroll down. This means that I need to figure out 2 things: 1. How to find out when my prototype has been scrolled to a certain position in comparison to the screen. 2. How to make the menu stick to the top of the screen.
Any ideas? The element that I'd like to stick to the top on scrolling down is the one with white bg below hero image.
