CSS: The Definitive Guide, 4th Edition

Appendix B. Basic Property Reference

Note that in addition to the options shown in the “Value Syntax” column of this appendix, all properties listed also accept the following global values: inherit, initial, and unset. They may in the future accept revert as well. These global values are not shown in the table for brevity and clarity.

Where a “P” is indicated for whether an element is animatable (the “Anim.” column), that means some but not all aspects of the property’s value can be animated.
