ParserLib CSS Parser

ParserLib is a CSS3 SAX-inspired parser written in JavaScript, designed for event-driven parsing of CSS stylesheets. It supports standard CSS syntax and offers a degree of validation for property names and values, though it is not exhaustive. The library is currently at version 1.1.1, with its most recent update focused on build file regeneration and minor CSS3 feature additions like `turn` units and nested media query support. Unlike AST-based parsers, ParserLib emits events during the parsing process rather than constructing a syntax tree, requiring developers to implement listeners for desired functionalities. It is built to operate in various JavaScript environments, including Node.js, Rhino, and directly in HTML pages, making it versatile for different project setups.
