Font style matcher

A screenshot of the font style matcher, displaying various sliders for CSS font properties for two different fonts.

This is pretty cool: you can use this to visually display the differences between two fonts - usually a fallback font and a web font - and adjust the various CSS font properties to match them as closely as possible to reduce the amount of page shifting that may occur when the web font loads. Also includes a longer paragraph at the bottom that can compare the two fonts either by overlaying them statically or by switching between them at a regular interval.
