//! CSS property values.
//!
//! Each property provides parsing and serialization support using the [Parse](super::traits::Parse)
//! and [ToCss](super::traits::ToCss) traits. Properties are fully parsed as defined by the CSS spec,
//! and printed in their canonical form. For example, most CSS properties are case-insensitive, and
//! may be written in various orders, but when printed they are lower cased as appropriate and in a
//! standard order.
//!
//! CSS properties often also contain many implicit values that are automatically filled in during
//! parsing when omitted. These are also omitted when possible during serialization. Many properties
//! also implement the [Default](std::default::Default) trait, which returns the initial value for the property.
//!
//! Shorthand properties are represented as structs containing fields for each of the sub-properties.
//! If some of the sub-properties are not specified in the shorthand, their default values are filled in.
//!
//! The [Property](Property) enum contains the values of all properties, and can be used to parse property values by name.
//! The [PropertyId](PropertyId) enum represents only property names, and not values and is used to refer to known properties.
//!
//! # Example
//!
//! This example shows how the `background` shorthand property is parsed and serialized. The `parse_string`
//! function parses the background into a structure with all missing fields filled in with their default values.
//! When printed using the `to_css_string` function, the components are in their canonical order, and default
//! values are removed.
//!
//! ```
//! use smallvec::smallvec;
//! use parcel_css::{
//!   properties::{Property, PropertyId, background::*},
//!   values::{url::Url, image::Image, color::CssColor, position::*, length::*},
//!   stylesheet::{ParserOptions, PrinterOptions},
//!   dependencies::Location,
//! };
//!
//! let background = Property::parse_string(
//!   PropertyId::from("background"),
//!   "url('img.png') repeat fixed 20px 10px / 50px 100px",
//!   ParserOptions::default()
//! ).unwrap();
//!
//! assert_eq!(
//!   background,
//!   Property::Background(smallvec![Background {
//!     image: Image::Url(Url {
//!       url: "img.png".into(),
//!       loc: Location { line: 1, column: 1 }
//!     }),
//!     color: CssColor::RGBA(cssparser::RGBA {
//!       red: 0,
//!       green: 0,
//!       blue: 0,
//!       alpha: 0
//!     }),
//!     position: BackgroundPosition {
//!       x: HorizontalPosition::Length(LengthPercentage::px(20.0)),
//!       y: VerticalPosition::Length(LengthPercentage::px(10.0)),
//!     },
//!     repeat: BackgroundRepeat {
//!       x: BackgroundRepeatKeyword::Repeat,
//!       y: BackgroundRepeatKeyword::Repeat,
//!     },
//!     size: BackgroundSize::Explicit {
//!       width: LengthPercentageOrAuto::LengthPercentage(LengthPercentage::px(50.0)),
//!       height: LengthPercentageOrAuto::LengthPercentage(LengthPercentage::px(100.0)),
//!     },
//!     attachment: BackgroundAttachment::Fixed,
//!     origin: BackgroundOrigin::PaddingBox,
//!     clip: BackgroundClip::BorderBox,
//!   }])
//! );
//!
//! assert_eq!(
//!   background.to_css_string(false, PrinterOptions::default()).unwrap(),
//!   r#"background: url("img.png") 20px 10px / 50px 100px fixed"#
//! );
//! ```
//!
//! If you have a [cssparser::Parser](cssparser::Parser) already, you can also use the `parse` and `to_css`
//! methods instead, rather than parsing from a string.
//!
//! # Unparsed and custom properties
//!
//! Custom and unknown properties are represented by the [CustomProperty](custom::CustomProperty) struct, and the
//! `Property::Custom` variant. The value of these properties is not parsed, and is stored as a raw
//! [TokenList](custom::TokenList), with the name as a string.
//!
//! If a known property is unable to be parsed, e.g. it contains `var()` references, then it is represented by the
//! [UnparsedProperty](custom::UnparsedProperty) struct, and the `Property::Unparsed` variant. The value is stored
//! as a raw [TokenList](custom::TokenList), with a [PropertyId](PropertyId) as the name.
