Value Meaning
Yes Indicates that the layout engine fully supports this property/element when valid values are used.
No Indicates that the property/element is completely ignored.
Partial Indicates that the property/element is understood, but that not all values are supported. Supported values are implemented correctly.
Incorrect Indicates that the property/element is understood, but that it is not implemented correctly in all cases.
Experimental Indicates that the property/element is understood, but supported under an alternate name. May be incomplete or buggy.
Dropped Indicates that the property/element is no longer supported.
Nightly build Indicates that the property/element is supported to some extent in an experimental/nightly build. Future support is expected.
