Features & Specs

  1. Full CSS parsing and DOM integration

    CSS4J provides a complete CSS parser, CSSOM implementation, and DOM integration for Java, allowing developers to parse, manipulate, and serialize CSS stylesheets programmatically with strong adherence to W3C specifications.

  2. Standards compliance

    The library aims for high fidelity to CSS specifications (CSS3/CSS4 features, selectors, values, etc.), making it useful for applications that need accurate CSS processing rather than approximate or simplified parsing.

  3. Support for advanced CSS features

    CSS4J supports modern CSS features such as custom properties (variables), calc(), media queries, and other CSS Values and Units specifications, which many lightweight Java CSS libraries lack.

  4. Useful for style computation

    It includes functionality for computing style values (cascading, specificity, inheritance), which is valuable for building tools like style checkers, browsers, or document renderers in Java.

  5. Open source and actively maintained

    The project is open source and has continued development, with releases addressing bug fixes and new CSS feature support, giving confidence in ongoing improvements and community support.
