Overview

The jekyll-katex plugin is a Jekyll plugin that allows for compile-time math rendering using the KaTeX library. KaTeX is a library for rendering math on the web using LaTeX. It offers faster rendering speed and renders equations to pure HTML instead of PNGs, setting it apart from MathJax. This plugin comes packaged with KaTeX 0.11.1, but users have the option to specify a different version in their Jekyll _config.yml file.
