It implements the W3C DOM Level 2 Style specification and supports CSS 2.1 and parts of CSS 3, including namespaces, media queries, page rules, and custom properties. The package does not render CSS\u2014it is purely for parsing, validation, and serialization.\n\nYou use it to load a CSS string or file, walk through rules and properties, modify values or priorities, add or remove rules, and serialize the result back to text. It depends on more_itertools and encutils for utility functions. The library is mature (first released in 2007) and actively maintained, though it is not thread-safe and requires Python 3.10 or later.","worth_installing":"Yes, if you need to parse, validate, or programmatically modify CSS as structured data. Install friction is low, maintenance is active, and there are no known security vulnerabilities. The copyleft license (LGPL-3.0-or-later) requires attention if you plan proprietary distribution. Not suitable for rendering or for thread-concurrent use."},"id":"cssutils","links":{"html":"https://skillfed.io/packages/cssutils","md":"https://skillfed.io/packages/cssutils.md","pypi":"https://pypi.org/project/cssutils/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-04-27","license_spdx":"LGPL-3.0-or-later","license_treatment":"copyleft","name":"cssutils","python_support":"supports_current","summary":"A CSS Cascading Style Sheets library for Python"},"popularity":{"monthly_downloads":9443090,"position":1533,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"2.15.0"}
