PHP CSS Parser

Parses CSS into a detailed object model including at-rules, selectors, and values, as evidenced by the extensive structure dumps in the README examples like the @font-face and @keyframes handling.

Offers multiple output formats via the OutputFormat class, allowing for compact, pretty, or custom CSS generation, demonstrated in the render() method with options like indentWithSpaces(4).

Handles a wide range of at-rules such as @charset, @font-face, and @keyframes, enabling complex stylesheet manipulations, shown in the example parsing and outputting @font-face and @keyframes blocks.

Provides methods like getAllDeclarationBlocks() and getAllValues() for easy access to CSS elements, simplifying common manipulation tasks as illustrated in use cases like prepending IDs to selectors.
