Documentation

type QueryableStyleSheet parser = QueryableStyleSheet' (ImportanceSplitter (PropertyExpander parser (OrderedRuleStore (WhereLowerer (InterpretedRuleStore StyleIndex))))) parser Source #

A parsed CSS stylesheet from which you can query styles to match an element.

data QueryableStyleSheet' store parser Source #

More generic version of QueryableStyleSheet.

Constructors

QueryableStyleSheet'

Fields

store :: store
Internal datastructure for efficient style lookup.
parser :: parser
The PropertyParser to use for property syntax validation.
priorities :: [Int]
Whether author, useragent, or user styles are currently being parsed. The tail of this list indicates which Cascade Layer is active.
layers :: Tree
Parse data for @layer, to give webdevs explicit control over the cascade.
layerNamespace :: [Text]

cascade :: PropertyParser p => QueryableStyleSheet p -> Element -> Props -> p -> p Source #

Facade over queryRules & cascade`. Instead of exposing pseudoelements to callers it exposes pseudoelements to the PropertyParser implementation.

cascade' :: PropertyParser p => [StyleRule'] -> Props -> p -> p Source #

Selects used property values from the given style rules, & populates into a new PropertyParser inheriting from the one given.

data VarParser a Source #

PropertyParser that lowers var() calls before forwarding to another.
