Variants
WithoutBlock(R)
The at-rule is expected to end with a ;
semicolon. Example: @import
.
The value is the finished representation of an at-rule
as returned by RuleListParser::next
or DeclarationListParser::next
.
WithBlock(P)
The at-rule is expected to have a a { /* ... */ }
block. Example: @media
The value is the representation of the "prelude" part of the rule.
OptionalBlock(P)
The at-rule may either have a block or end with a semicolon.
This is mostly for testing. As of this writing no real CSS at-rule behaves like this.
The value is the representation of the "prelude" part of the rule.
