The Best Headline in the World! But the Scroller Still Needs Work.

After seeing this pen which uses a body::before pseudo-element, and this one which uses multiple background gradients, I just had to pull it apart and understand what was happening. It's a neat trick!

I opted for the multiple backgrounds method for this, but both techniques have the same short-comings: beyond a simple page of text, the issues get quite complicated...

Problems

Setting html & body to height: 100% breaks the scroll indicator.
Content obscures the scroll indicator as it goes "above" it.
Scrolling horizontally illuminates scroll indicator layout limitations.

Opportunities

Horizontal (as opposed to a vertical) scrolling indicator.
Function/Mixin to use this without needing to build it each time.
