scroll-into-center

This script provides a polyfill to support unstandardised Element.scrollIntoCenter(), similar to the standard scrollIntoView. The functionality has been suggested before as a possible addition to scrollIntoView, which always aligns the element with the top of the view.

Usage

Simply include the script, and every DOM element will have the method scrollIntoCenter({options}).

option fields:

• vertical: scalar between 0 and 1. Default = 0.5. The value 0 aligns the top of the element with the top of the view, 1 aligns the bottom with the bottom, and 0.5 (default) puts the center in the center.

• horizontal: scalar between 0 and 1. Default = 0.5. Functions like vertical.
