MathJax

MathJax is an open-source JavaScript display engine that renders mathematical notation on web pages. It accepts input in LaTeX, MathML, and AsciiMath and produces high-quality, accessible mathematics that works across browsers and devices. Rendered math can use scalable vector graphics (SVG) or HTML-CSS output, and MathJax runs in the client, requiring no server-side processing.

MathJax is maintained by a community of developers and organizations in cooperation with the American Mathematical Society. It is released under the Apache License 2.0 and is available for loading from a content delivery network (CDN) or for local installation. The project emphasizes compatibility with various hosting environments and content ecosystems.

Its architecture uses input processors (input jax) for LaTeX, MathML, and AsciiMath, and output processors (output jax) for SVG, HTML-CSS, and MathML-CSS. Users can customize behavior through configuration options and extensions, including delimiters, equation numbering, and menu features. It also emphasizes accessibility, providing semantic MathML where possible and improving screen reader compatibility.

MathJax is widely used in educational websites, wikis, and content management systems to render mathematics reliably in the browser. It supports responsive rendering, font scaling, and high-quality typography on devices ranging from desktops to mobile devices, helping ensure consistent mathematical presentation across platforms.
