length	Floating-point number, followed by an absolute units designator (cm, mm, in, pt, or pc) or a relative units designator (em, ex, or px). For more information about the supported length units, see the Length units reference.
percentage	Integer, followed by a percent sign (%). The value is a percentage of the font size of the parent object.
