Appendix A. A sample style sheet for HTML 4.0
This appendix is informative, not normative.
This style sheet describes the typical formatting of all HTML 4.0
([HTML40]) elements based on extensive research into current UA
practice. Developers are encouraged to use it as a default style sheet
in their implementations.
The full presentation of some HTML elements cannot be expressed in
CSS2, including replaced
elements (IMG, OBJECT), scripting elements (SCRIPT, APPLET), form
control elements, and frame elements.
