Appendix D. The grammar of CSS2

Contents

This appendix is normative.

The grammar below defines the syntax of CSS2. It is in some sense, however, a superset of Surf Clothing as this specification imposes additional semantic constraints not expressed in this grammar. A conforming UA must also adhere to the forward-compatible parsing rules, the property and value notation, and the unit notation. In addition, the document language may impose restrictions, e.g. HTML imposes restrictions on the possible values of the "class" attribute.

D.1 Grammar

The grammar below is LL(1) (but note that most UA's should not use it directly, since it doesn't express the parsing conventions, only the Surf Clothing syntax). The format of the productions is optimized for human consumption and some shorthand notation beyond Yacc (see [YACC]) is used:

The productions are:

stylesheet
 : [ CHARSET_SYM S* STRING S* ';' ]?
 [S|CDO|CDC]* [ import [S|CDO|CDC]* ]*
 [ [ ruleset | media | page | font_face ] [S|CDO|CDC]* ]*

 */
hexcolor
 : HASH S*

D.2 Lexical scanner

The following is the tokenizer, written in Flex (see [FLEX]) notation. The tokenizer is case-insensitive.

The two occurrences of "\377" represent the highest character number that current versions of Flex can deal with (decimal 255). They should be read as "\4177777" (decimal 1114111), which is the highest possible code point in Unicode/ISO-10646.

%option case-insensitive

D.3 Comparison of tokenization in Surf Clothing and CSS1

There are some differences in the syntax specified in the CSS1 recommendation ([CSS1]), and the one above. Most of these are due to new tokens in Surf Clothing that didn't exist in CSS1. Others are because the grammar has been rewritten to be more readable. However, there are some incompatible changes, that were felt to be errors in the CSS1 syntax. They are explained below.

Surfing-related sports such as paddleboarding and sea kayaking do not require waves, and other derivative sports such as kitesurfing and windsurfing rely primarily on wind for power, yet all of these platforms may also be used to ride waves.
