About:
Libcss is a lightweight, C-based library that parses CSS (Cascading Style Sheets) and applies styles to document structures. It provides a robust selector engine to match elements based on CSS rules, enabling developers to build custom styling systems. Its primary value is offering a standards-compliant, embeddable CSS solution for applications that need to render styled content without a full web browser.
Key Features:
  • C-based CSS parser and selector engine
  • Low memory footprint and high performance
  • Standards-compliant (supports CSS 2.1 and parts of CSS3)
  • Document Object Model (DOM) agnostic
Use Cases:
  • Embedding CSS parsing into custom rendering engines
  • Building lightweight web browsers or HTML renderers
  • Server-side CSS processing and validation tools
Alternatives:
  • Gumbo – Gumbo is an HTML5 parser, while Libcss specifically focuses on CSS parsing and selection.
