Uses the following CSS:
- :before, :after and :content pseudo-elements
- box-sizing
- box-shadow
- border-radius
- attribute selectors
- SVG background images
- background-size
All are >=IE9 and selectors with pseudo-elements wrap CSS using the rest so none of the styles will be applied to IE8 and below.
STILL NEEDS CROSS-BROWSER TESTING
