data CssSelector Source #
Define complex selector.
Constructors

type CssSelectorRule = [CssSelector] Source #
A CssSelectorRule is a list of all the elements that must be meet in a depth first search fashion.
Represent a CSS selector and the different declarations to apply to the matched elemens.

class CssMatcheable a where Source #
Interface for elements to be matched against some CssRule.
Methods
cssIdOf :: a -> Maybe Text Source #
For an element, tell its optional ID attribute.
cssClassOf :: a -> [Text] Source #
For an element, return all of it's class attributes.
cssNameOf :: a -> Text Source #
Return the name of the tagname of the element
cssAttribOf :: a -> Text -> Maybe Text Source #
Return a value of a given attribute if present
type CssContext a = [[a]] Source #
Represent a zipper in depth at the first list level, and the previous nodes at in the second list level.
Alias describing a "dot per inch" information used for size calculation (see toUserUnit).
Encode complex number possibly dependant to the current render size.
Constructors
| Num Double | Simple coordinate in current user coordinate. |
| Px Double | With suffix "px" |
| Em Double | Number relative to the current font size. |
| Percent Double | Number relative to the current viewport size. |
| Pc Double | |
| Mm Double | Number in millimeters, relative to DPI. |
| Cm Double | Number in centimeters, relative to DPI. |
| Point Double | Number in points, relative to DPI. |
| Inches Double | Number in inches, relative to DPI. |
Instances
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.
mapNumber :: (Double -> Double) -> Number -> Number Source #
Helper function to modify inner value of a number
tserialize :: TextBuildable a => a -> Builder Source #
Serialize an element to a text builder.
