Interface ContentFunction

Known Implementing Classes:
AttrValueFunction, CountersValueFunction, CounterValueFunction, DateValueFunction, ElementsFunction, FormatValueFunction, PendingFunction, StringValueFunction, UrlValueFunction

public interface ContentFunction

A content function is only valid when evaluating either the 'content' property or the 'string-set' property. These functions produce ContentToken. ContentFunctions are only valid as first-level functions. That means, when evaluating nested function calls like 'url(attr(blah))', the URL function will be resolved as ContentFunction, but the attr-function will be resolved as ordinary CSSValue function.
