the web. + + * **Fast:** KaTeX renders its math synchronously and doesn't need to reflow the page. See how it compares to a competitor in [this speed test](https://www.intmath.com/cg5/katex-mathjax-comparison.php). + * **Print quality:** KaTeX's layout is based on Donald Knuth's TeX, the gold standard for math typesetting. + * **Self contained:** KaTeX has no dependencies and can easily be bundled with your website resources. + * **Server side rendering:** KaTeX produces the same output regardless of browser or environment, so you can pre-render expressions using Node.js and send them as plain HTML. + +KaTeX is compatible with all major browsers, including Chrome, Safari, Firefox, Opera, Edge, and IE 11. + +KaTeX supports much (but not all) of LaTeX and many LaTeX packages. See the [list of supported functions](https://katex.org/docs/supported.html). + +Try out KaTeX [on the demo page](https://katex.org/#demo)! + +## Getting started + +### Starter template + +```html + + + + + + + + + + + + + ... + +``` + +You can also [download KaTeX](https://github.com/KaTeX/KaTeX/releases) and host it yourself. + +For details on how to configure auto-render extension, refer to [the documentation](https://katex.org/docs/autorender.html). + +### API + +Call `katex.render` to render a TeX expression directly into a DOM element. +For example: + +```js +katex.render("c = \\pm\\sqrt{a^2 + b^2}", element, { + throwOnError: false +}); +``` + +Call `katex.renderToString` to generate an HTML string of the rendered math, +e.g., for server-side rendering. For example: + +```js +var html = katex.renderToString("c = \\pm\\sqrt{a^2 + b^2}", { + throwOnError: false +}); +// '...' +``` + +Make sure to include the CSS and font files in both cases. +If you are doing all rendering on the server, there is no need to include the +JavaScript on the client. + +The examples above use the `throwOnError: false` option, which renders invalid +inputs as the TeX source code in red (by default), with the error message as +hover text. For other available options, see the +[API documentation](https://katex.org/docs/api.html), +[options documentation](https://katex.org/docs/options.html), and +[handling errors documentation](https://katex.org/docs/error.html). + +## Demo and Documentation + +Learn more about using KaTeX [on the website](https://katex.org)! + +## Contributors + +### Code Contributors + +This project exists thanks to all the people who contribute code.
