				-
			
 
				-KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on 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
			
 
				-<!DOCTYPE html>
			
 
				-<!-- KaTeX requires the use of the HTML5 doctype. Without it, KaTeX may not render properly -->
			
 
				-<html>
			
 
				-  <head>
			
 
				-    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.16.2/dist/katex.min.css" integrity="sha384-bYdxxUwYipFNohQlHt0bjN/LCpueqWz13HufFEV1SUatKs1cm4L6fFgCi1jT643X" crossorigin="anonymous">
			
 
				-
			
 
				-    <!-- The loading of KaTeX is deferred to speed up page rendering -->
			
 
				-    <script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.2/dist/katex.min.js" integrity="sha384-Qsn9KnoKISj6dI8g7p1HBlNpVx0I8p1SvlwOldgi3IorMle61nQy4zEahWYtljaz" crossorigin="anonymous"></script>
			
 
				-
			
 
				-    <!-- To automatically render math in text elements, include the auto-render extension: -->
			
 
				-    <script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.2/dist/contrib/auto-render.min.js" integrity="sha384-+VBxd3r6XgURycqtZ117nYw44OOcIax56Z4dCRWbxyPt0Koah1uHoK0o4+/RRE05" crossorigin="anonymous"
			
 
				-        onload="renderMathInElement(document.body);"></script>
			
 
				-  </head>
			
 
				-  ...
			
 
				-</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
			
 
				-});
			
 
				-// '<span class="katex">...</span>'
			
 
				-```
			
 
				-
			
 
				-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).

				- *  This file implements a KaTeX version of mhchem version 3.3.0.
			
 
				- *  It is adapted from MathJax/extensions/TeX/mhchem.js
			
 
				- *  It differs from the MathJax version as follows:
			
 
				- *    1. The interface is changed so that it can be called from KaTeX, not MathJax.
			
 
				- *    2. \rlap and \llap are replaced with \mathrlap and \mathllap.
			
 
				- *    3. Four lines of code are edited in order to use \raisebox instead of \raise.
			
 
				- *    4. The reaction arrow code is simplified. All reaction arrows are rendered
			
 
				- *       using KaTeX extensible arrows instead of building non-extensible arrows.
			
 
				- *    5. \tripledash vertical alignment is slightly adjusted.
			
 
				- *
			
 
				- *    This code, as other KaTeX code, is released under the MIT license.

				- *  KaTeX mhchem.js
			
 
				- *
			
 
				- *  This file implements a KaTeX version of mhchem version 3.3.0.
			
 
				- *  It is adapted from MathJax/extensions/TeX/mhchem.js
			
 
				- *  It differs from the MathJax version as follows:
			
 
				- *    1. The interface is changed so that it can be called from KaTeX, not MathJax.
			
 
				- *    2. \rlap and \llap are replaced with \mathrlap and \mathllap.
			
 
				- *    3. Four lines of code are edited in order to use \raisebox instead of \raise.
			
 
				- *    4. The reaction arrow code is simplified. All reaction arrows are rendered
			
 
				- *       using KaTeX extensible arrows instead of building non-extensible arrows.
			
 
				- *    5. \tripledash vertical alignment is slightly adjusted.
			
 
				- *
			
 
				- *    This code, as other KaTeX code, is released under the MIT license.
