Detailed Description

Parser of a style element/option.

This class parses the content of a style element or a style option and preprocesses it.

The result of the parser is forwarded to derived parsers by the methods SelectorParsed() and DeclarationParsed(). Example: H1, H2 { font-weight: bold; text-align: right } | | | | | | | DeclP( 'text-align', 'right' ) | | DeclP( 'font-weight', 'bold' ) | SelP( 'H2', false ) SelP( 'H1', true )
