type CssSelectorRule = [CssSelector] Source

A CssSelectorRule is a list of all the elements that must be meet in a depth first search fashion.

data CssRule Source

Represent a CSS selector and the different declarations to apply to the matched elemens.

Constructors

CssRule

Show Number Source

serializeNumber :: Number -> String Source

Encode the number to string which can be used in a CSS or a svg attributes.

findMatchingDeclarations :: CssMatcheable a => [CssRule] -> CssContext a -> [CssDeclaration] Source

Given CSS rules, find all the declaration to apply to the element in a given context.

toUserUnit :: Dpi -> Number -> Number Source

This function replace all device dependant units to user units given it's DPI configuration. Preserve percentage and "em" notation.
