// REM CALC by Foundation

// New Syntax, allows to optionally calculate on a different base value to counter compounding effect of rem's.
// Call with 1, 2, 3 or 4 parameters, 'px' is not required but supported:
//
//   rem-calc(10 20 30px 40);
//
// Space delimited, if you want to delimit using comma's, wrap it in another pair of brackets
//
//   rem-calc((10, 20, 30, 40px));
//
// Optionally call with a different base (eg: 8px) to calculate rem.
//
//   rem-calc(16px 32px 48px, 8px);
//
// If you require to comma separate your list
//
//   rem-calc((16px, 32px, 48), 8px);

// This is the default html and body font-size for the base rem value.
