Notes
Support can be somewhat emulated in older versions of IE using the non-standard expression() syntax.
Due to the way browsers handle sub-pixel rounding differently, layouts using calc() expressions may have unexpected results.
Partial support in Android Browser 4.4 refers to the browser lacking the ability to multiply and divide values.
Partial support in IE9 refers to the browser crashing when used as a
background-positionvalue.
- * Partial support with prefix.
