Appendix B. HTML 2.0 Style Sheet

The style sheet provided in this chapter was excerpted from the CSS1 specification and is included here to give authors an idea of how legacy browser behavior in handling HTML can be reproduced, or at least approximated, using CSS1 rules. A thorough understanding of this style sheet is a good first step to understanding how CSS1 operates. The simpler HTML 2.0 style sheet is reproduced here in order to minimize complexity and possible confusion. A suggested style sheet for HTML 3.2 is also available on the W3C web site, as part of the CSS2 specification.

This HTML 2.0 style sheet was written by Todd Fahrner, in accordance with the suggested rendering in the HTML 2.0 specification:

 BODY { 
  margin: 1em;
  font-family: serif;
  line-height: 1.1;
  background: white;
  color: black; 
 }

 DT, DD, ADDRESS, BLOCKQUOTE, PRE, BR, HR { display: block }

 B, STRONG, I, EM, CITE, VAR, TT, CODE, KBD, SAMP, 
 IMG, SPAN { display: inline }

 LI { display: list-item }

 H1, H2, H3, H4 { margin-top: 1em; margin-bottom: 1em }
 H5, H6 { margin-top: 1em }
 H1 { text-align: center }
 H1, H2, H4, H6 { font-weight: bold }
 H3, H5 { font-style: italic }

 H1 { font-size: xx-large }

 DT { margin-bottom: 0 }
 DD { margin-top: 0; margin-left: 3em }

 HR { border-top: solid }   /* 'border-bottom' could also have been used */

 A:link { color: blue }    /* unvisited link */
 A:visited { color: red }   /* visited links */
 A:active { color: lime }   /* active links */

 /* setting the anchor border around IMG elements
