Style properties can be of types String or Number. They can also be Arrays of these types. In addition to a type, style properties also have a format (Length, Time, or Color) that describes the valid values of the property. Some properties appear to be of type Boolean (taking a value of true or false), but these are Strings that are interpreted as Boolean values. This section describes these formats.
