// Function: size // Simple Rem based multiplier // - Use to convert pixel dimension to REM units // - Default is 0.5rem (8px) which is our Spacing unit. // - Optional: Add variable based value to $unit when 1rem is not 16px. // E.g: size(5) will output: 2.5rem which is 40px; @function size($multiplier, $unit:0.5rem) { @return $multiplier * $unit; }
