# H. Style sheet for XHTML 2

This appendix is normative.

This Appendix defines a normative [CSS2] style sheet for XHTML 2. While visual user agents implementing XHTML 2 are not required to support CSS2, their default behavior should be as if the following CSS2 styles are in effect. Note that this default behavior can be overridden by any number of things - including, for example, user-defined preferences.
