How TO - Change Background on Scroll

Changing Background color when user scrolls has set trend in the industry and is being used quiet often for one page websites, special pages in projects and more places.

If not the color the height or the break points are embedded in Javascript. So I want to make a script that can take values for background-color and break point where the color transition has to be triggered from the HTML markup, this is gonna make the script reusable and easy to update work. Next task is to get the break points which is easy but isn't hard coded that mean's I'm gonna have to get it dynamically, this is what makes this script work with web page having elements of different height and also the background-color from the above markup.

Starting with Zero for the first element. The scroll height is obtained from. With Break Point and current position of scroll bar in hand all it's left is to change the background color once they are matched. Before we can do that, the calculated break points and the corresponding background color has to be stored some where easily accessible, else we will end up doing the whole calculations every time the user scrolls. The height and the corresponding color is stored in a single dimensional array, with the array index as the sum of heights of elements up to the current element from top the break point and the value as the background color of the element. A typical array will be like. A simple search in the array will give the background value, In this experiment I have used Binary search.
