Description
-----------
[CSS](https://css-raku.github.io/CSS-raku) is a module for parsing style-sheets and applying them to HTML or XML documents.
This module aims to be W3C compliant and complete, including: style-sheets, media specific and inline styling and the application of HTML specific styling (based on tags and attributes).
Methods
-------
### method new
method new(
LibXML::Document :$doc!, # document to be styled.
CSS::Stylesheet :$stylesheet!, # stylesheet to apply
CSS::TagSet :$tag-set, # tag-specific styling
CSS::Media :$media, # target media
Bool :$inherit = True, # perform property inheritance
) returns CSS;
In particular, the `CSS::TagSet :$tag-set` options specifies a tag-specific styler; For example CSS::TagSet::XHTML.
### method style
multi method style(LibXML::Element:D $elem) returns CSS::Properties;
multi method style(Str:D $xpath) returns CSS::Properties;
Computes a style for an individual element, or XPath to an element.
### method prune
method prune(LibXML::Element $node? --> LibXML::Element)
Removes all XML nodes with CSS property `display:none;`, giving an approximate representation of a CSS rendering tree.
For example, for a XHTML tag-set the `head` element will be removed, along with any other elements that have had `display:none;' applied to them via inline CSS or CSS Selectors.
By default, this method acts on the root element of the associated $.doc XML document.
