Spaces around *

Why is this capitalized?

This need wrapping. CSSValueINFINITY is ugly.

I would wrap this like:

return {
    { CSSValuePi, CSSUnitType::CSS_NUMBER, piDouble }, { CSSValueE, CSSUnitType::CSS_NUMBER, std::exp(1.0) },
    { CSSValueNegativeInfinity, CSSUnitType::CSS_NUMBER, -1 * std::numeric_limits<double>::infinity() },
    { CSSValueInfinity, CSSUnitType::CSS_NUMBER, std::numeric_limits<double>::infinity() },
    { CSSValueNaN, CSSUnitType::CSS_NUMBER, std::numeric_limits<double>::quiet_NaN() },
};
