The -Webkit-scrollbar challenge

dabblet.css

/**
 * The -Webkit-scrollbar challenge
 * * * * * * * * * * * * * * * * * * * * * * * * * * * *
 * Make the first div’s scrollbar like the second’s 
 * without changing the styling of the div (i.e. you
 * can only change the ::-webkit-scrollbar-* rules
 * * * * * * * * * * * * * * * * * * * * * * * * * * * *
 * It doesn't matter if the second div doesn't look the same
 * after your changes, it's only there to show you how the
 * end result should look.
 * * * * * * * * * * * * * * * * * * * * * * * * * * * *
 * Basically the goal is to see if we can apply some kind
 * of margin to the scrollbars to offset them from the edge
