HTMLCSS is a lightweight HTML/CSS parser written in C that allows applications to prepare a HTML document for rendering or conversion. Features include:
- HTML 5 markup parser
- CSS 3 stylesheet parser
- GIF/JPEG/PNG image file parser (metadata only)
- Functions to calculate CSS properties for a given node in a HTML document
- Functions to extract HTML "runs" consisting of CSS properties, content strings, and image references that can be rendered directly, including the :before and :after content from a stylesheet
- A device API for reporting capabilities and handling fonts
- A memory pool for efficiently storing and caching strings and CSS properties
- A URL API to support fetching remote resources
HTMLCSS does not support dynamic HTML content created using Javascript in a HTML document, as such content is typically used for interactive/dynamic web pages while HTMLCSS is intended for use with static content.
HTMLCSS requires a C99 compiler like GCC, Clang, or Visual C, along with
POSIX-compliant make and sh programs (Linux/Unix), Visual Studio (Windows),
and/or Xcode (macOS) for doing the build. The only required library is ZLIB
(1.1 or later) for compression support.
Documentation can be found in the "htmlcss.html" file.
