CssTranslation(

1. CssNumericValue x,
2. CssNumericValue y,
3. [CssNumericValue? z]

)

## Implementation

    factory CssTranslation(CssNumericValue x, CssNumericValue y,
        [CssNumericValue? z]) {
      if ((y is CssNumericValue) && (x is CssNumericValue) && z == null) {
        return CssTranslation._create_1(x, y);
      }
      if ((z is CssNumericValue) &&
          (y is CssNumericValue) &&
          (x is CssNumericValue)) {
        return CssTranslation._create_2(x, y, z);
      }
      throw new ArgumentError("Incorrect number or type of arguments");
