Flags
ahem, invalid
Assertion
The 'font-size' property sets a minimum minus one length value in pixels is invalid; such 'font-size' declaration should be ignored. Then the 'font-size' property value can be determined by computed font-size of containers and from cascade mechanisms (user, author, user agent).
