Module javafx.graphics

# Package javafx.css

Provides API for making properties styleable via CSS and for supporting pseudo-class state.

The JavaFX Scene Graph provides the facility to style nodes using CSS (Cascading Style Sheets). The `Node` class contains `id`, `styleClass`, and `style` variables which are used by CSS selectors to find nodes to which styles should be applied. The `Scene` class and `Parent` class contain a the `stylesheets` variable which is a list of URLs that reference CSS style sheets that are to be applied to the nodes within that scene or parent.

The primary classes in this package are:

`CssMetaData`
  Defines the CSS property and provides a link back to the `StyleableProperty`. By convention, classes that have CssMetaData implement a `public static List<CssMetaData<? extends Styleable>> getClassCssMetaData()` method that allows other classes to include CssMetaData from an inherited class. The method `getCssMetaData()` should be overridden to return `getClassCssMetaData()`. The CSS implementation frequently calls `getCssMetaData()`. It is strongly recommended that the returned list be a `final static`.
`StyleableProperty`
  Defines the interface that the CSS implementation uses to set values on a property and provides a link back to the `CssMetaData` that corresponds to the property. The `StyleablePropertyFactory` greatly simplifies creating a StyleableProperty and its corresponding CssMetaData.
`PseudoClass`
  Defines a pseudo-class which can be set or cleared via the method `pseudoClassStateChanged`.

For further information about CSS, how to apply CSS styles to nodes, and what properties are available for styling, see the CSS Reference Guide.

  CssParser.ParseError.PropertySetError | Encapsulates errors arising from applying a style to a Node.
  CssParser.ParseError.StringParsingError | Encapsulate errors arising from parsing when the style is not an in-line style nor is the style from a stylesheet.
  CssParser.ParseError.StylesheetParsingError | Encapsulate errors arising from parsing of stylesheet files
  Declaration |
  FontCssMetaData<S extends Styleable> | An partial implementation of CssMetaData for Font properties which includes the font sub-properties: weight, style, family and size.
  FontFace | A FontFace is a @font-face definition from CSS file
  Match | Used by `Rule` to determine whether or not the selector applies to a given object.
  ParsedValue<V,​T> | A representation of a parsed CSS value.
  PseudoClass | PseudoClass represents one unique pseudo-class state.
  Rule |
  Selector | Used by CSSRule to determine whether or not the selector applies to a given object.
