//! This module provides mappings between CSS properties and their abbreviations (short syntax).
//!
//! It allows for retrieving the full CSS property name given either the full name or its abbreviation,
//! as well as retrieving the abbreviation given the full name.
//!
//! The module also provides a list of all components (full names and abbreviations).
