Convert a value into the proper css writable value. The style name `name`
should be logical (no hyphens), as specified
in `CSSProperty.isUnitlessNumber`.

@param {string} name CSS property name such as `topMargin`.
@param {*} value CSS property value such as `10px`.
@return {string} Normalized style value with dimensions applied.
