What information would we want to display for this? I took an initial stab at the src/_aspect-ratios.css file and came up with the following:

/* 
 * BROWSER COMPATIBILITY
 * 
 * Attributes used: height, position, padding-bottom, top, right, bottom, left, width, z-index
 *
 * DESKTOP:
 * Chrome: 1
 * Edge: 12
 * Firefox: 1
 * Internet Explorer: 5.5
 * Opera: 7
 * Safari: 1
 *
 * MOBILE:
 * Android Webview: 1
 * Chrome for Android: 18
 * Edge Mobile: Yes
 * Firefox for Android: 4
 * Opera for Android: 1
 * Safari on iOS: 1
 * Samsung Internet: Yes
 *
 * */

Anyone have thoughts on this? It'd also important to call out things like media queries (IE9+) and different unit types.

What's the state of IE support?
