+## In-browser rendering
+Call `katex.render` with a TeX expression and a DOM element to render into:
+
+```js
+katex.render("c = \\pm\\sqrt{a^2 + b^2}", element, {
+ throwOnError: false
+});
+```
+
+To avoid escaping the backslash (double backslash), you can use
+[`String.raw`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/raw)
+(but beware that `${`, `\u` and `\x` may still need escaping):
+```js
+katex.render(String.raw`c = \pm\sqrt{a^2 + b^2}`, element, {
+ throwOnError: false
+});
+```
+
+## Server-side rendering or rendering to a string
+To generate HTML on the server or to generate an HTML string of the rendered math, you can use `katex.renderToString`:
+
+```js
+var html = katex.renderToString("c = \\pm\\sqrt{a^2 + b^2}", {
+ throwOnError: false
+});
+// '...'
+```
+
+## Handling errors
+
+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. Without this option, invalid LaTeX will cause a
+`katex.ParseError` exception to be thrown. See [handling errors](error.md).
+
+## Configuring KaTeX
+
+The last argument to `katex.render` and `katex.renderToString` can contain
+[a variety of rendering options](options.md).
+
+## Persistent Macros
+
+KaTeX’s [macro documentation](supported.html#gdef) tells the author that `\gdef` will create a macro that persists between KaTeX elements. In order to enable that persistence, you must create one shared `macros` object that you pass into every call to `katex.render` or `katex.renderToString`. (Do not create a fresh `macros` object for each call.)
+
+For example, suppose that you have an array `mathElements` of DOM elements that contain math. Then you could write this code:
+
+```js
+const macros = {};
+for (let element of mathElements) {
+ katex.render(element.textContent, element, {
+ throwOnError: false,
+ macros
+ };
+}
+```
+
+Notice that you create the `macros` object outside the loop. If an author uses `\gdef`, KaTeX will insert that macro definition into the `macros` object and since `macros` continues to exist between calls to `katex.render`, `\gdef` macros will persist between `mathElements`.
+
+### Security of Persistent Macros
+
+Persistent macros can change the behavior of KaTeX (e.g. redefining standard commands), so for security, such a setup should be used only for multiple elements of common trust. For example, you might enable persistent macros within a message posted by a single user (by creating a `macros` object for that message), but you probably should not enable persistent macros across multiple messages posted by multiple users.

+This is an extension to automatically render all of the math inside of text. It

+Alternatively, you can call the `renderMathInElement` when (or after) the
+[`DOMContentLoaded` event](https://developer.mozilla.org/ko/docs/Web/Reference/Events/DOMContentLoaded)

+
+## API
+This extension exposes a single function, `window.renderMathInElement`, with
+the following API:
+
+```js
+function renderMathInElement(elem, options)
+```
+
+`elem` is an HTML DOM element. The function will recursively search for text
+nodes inside this element and render the math in them.
+
+`options` is an optional object argument that can have the same keys as [the
+object passed to `katex.render`](https://github.com/KaTeX/KaTeX/#rendering-options),
+in addition to two auto-render-specific keys:
+
+- `delimiters`: This is a list of delimiters to look for math, processed in
+ the same order as the list. Each delimiter has three properties:
+
+ - `left`: A string which starts the math expression (i.e. the left delimiter).
+ - `right`: A string which ends the math expression (i.e. the right delimiter).
+ - `display`: A boolean of whether the math in the expression should be
+ rendered in display mode or not.
+
+ The default value is:
+
+ ```js
+ [
+ {left: "$$", right: "$$", display: true},
+ {left: "\\(", right: "\\)", display: false},
+ {left: "\\begin{equation}", right: "\\end{equation}", display: true},
+ {left: "\\begin{align}", right: "\\end{align}", display: true},
+ {left: "\\begin{alignat}", right: "\\end{alignat}", display: true},
+ {left: "\\begin{gather}", right: "\\end{gather}", display: true},
+ {left: "\\begin{CD}", right: "\\end{CD}", display: true},
+ {left: "\\[", right: "\\]", display: true}
+ ]
+ ```
+
+ If you want to add support for inline math via `$...$`, be sure to list it
+ *after* `$$`, as in the following. (Because rules are processed in order,
+ putting a `$` rule first would catch `$$` as an empty math expression.)
+
+ ```js
+ [
+ {left: "$$", right: "$$", display: true},
+ {left: "$", right: "$", display: false},
+ {left: "\\(", right: "\\)", display: false},
+ {left: "\\[", right: "\\]", display: true}
+ ]
+ ```
+
+- `ignoredTags`: This is a list of DOM node types to ignore when recursing
+ through. The default value is
+ `["script", "noscript", "style", "textarea", "pre", "code", "option"]`.
+
+- `ignoredClasses`: This is a list of DOM node class names to ignore when
+ recursing through. By default, this value is not set.
+
+- `errorCallback`: A callback method returning a message and an error stack
+ in case of an critical error during rendering. The default uses `console.error`.
+
+- `preProcess`: A callback function, `(math: string) => string`, used to process
+ math expressions before rendering.
+
+The `displayMode` property of the options object is ignored, and is
+instead taken from the `display` key of the corresponding entry in the
+`delimiters` key.
+
+The same `options.macros` object (which defaults to an empty object `{}`)
+is passed into several calls to `katex.render`, so that consecutive equations
+can build up shared macros by `\gdef`.

+---
+By changing the variables in the `fonts.less` file at the [katex-fonts submodule](https://github.com/KaTeX/katex-fonts/),
+several properties of the way fonts are used can be changed.
+
+## Font size and lengths
+By default, KaTeX math is rendered in a 1.21× larger font than the surrounding
+context, which makes super- and subscripts easier to read. You can control
+this using CSS, for example, to set to 1.1×:
+
+```css
+.katex { font-size: 1.1em; }
+```
+
+KaTeX supports all TeX units, including absolute units like `cm` and `in`.
+Absolute units are currently scaled relative to the default TeX font size of
+10pt, so that `\kern1cm` produces the same results as `\kern2.845275em`.
+As a result, relative and absolute units are both uniformly scaled relative
+to LaTeX with a 10pt font; for example, the rectangle `\rule{1cm}{1em}` has
+the same aspect ratio in KaTeX as in LaTeX. However, because most browsers
+default to a larger font size, this typically means that a 1cm kern in KaTeX
+will appear larger than 1cm in browser units.
+
+## Kinds of fonts used
+
+KaTeX provides fonts in three different formats: `ttf`, `woff`, and `woff2`.
+
+- `ttf`s are included to support very old browsers and local installation. [Browser support](https://caniuse.com/#feat=ttf)
+- `woff` is the format that is most widely supported (all modern browsers support it), so it probably provides the most benefit to being included. [Browser support](https://caniuse.com/#feat=woff)
+- `woff2`s are included for modern browsers, because they are much smaller and faster to load. [Browser support](https://caniuse.com/#feat=woff2)
+
+KaTeX will automatically include only necessary fonts for target environments
+specified by [Browserslist config](https://github.com/browserslist/browserslist#queries).
+
+To force a font type to be included or excluded, set `USE_(FONT NAME)` environment
+variable to `"true"` or `"false"`, respectively.
+
+## Location of font files
+
+The default build of KaTeX expects the KaTeX fonts to be located in a directory called `fonts` which is a sibling of the `katex.min.css` stylesheet. This can be changed as follows:
+
+1. At the top of the [fonts.less](https://github.com/KaTeX/katex-fonts/blob/master/fonts.less) file, set `@font-folder` to the location of your fonts. You can use relative or absolute paths, so setting it to `"/fonts"` would cause it to search for the fonts in a root `fonts` folder, while `"../fonts"` would search in a `fonts` directory one level above the `katex.min.css` file.
+2. Rebuild KaTeX by running `yarn build` from the top-level directory.
+3. Use the newly generated `dist/katex.min.css` file, and place the fonts where you indicated.

+
+As of KaTeX 1.0, we've changed how MacroExpander and Parser work in order to close
+some gaps between KaTeX and LaTeX and therefore there may be breaking changes.
+
+## Macro arguments
+Tokens will not be expanded while parsing a macro argument. For example, `\frac\foo\foo`,
+where the `\foo` is defined as `12`, will be parsed as `\frac{12}{12}`, not
+`\frac{1}{2}12`. To expand the argument before parsing, `\expandafter` can
+be used like `\expandafter\frac\foo\foo`.
+
+## `\def`
+`\def` no longer accepts a control sequence enclosed in braces. For example,
+`\def{\foo}{}` no longer works and should be changed to `\def\foo{}`.
+
+It also no longer accepts replacement text not enclosed in braces. For example,
+`\def\foo1` no longer works and should be changed to `\def\foo{1}`.
+
+## `\newline` and `\cr`
+`\newline` and `\cr` no longer takes an optional size argument. To specify vertical
+spacing, `\\` should be used.
+
+## `\cfrac`, `\color`, `\textcolor`, `\colorbox`, `\fcolorbox`
+They are no longer allowed as an argument to primitive commands, such as `\sqrt`
+(without the optional argument) and super/subscript. For example,
+`\sqrt\textcolor{red}{x}` no longer works and should be changed to
+`\sqrt{\textcolor{red}{x}}`.

+You can provide an object of options as the last argument to [`katex.render` and `katex.renderToString`](api.md). Available options are:
+
+- `displayMode`: `boolean`. If `true` the math will be rendered in display mode, which will put the math in display style (so `\int` and `\sum` are large, for example), and will center the math on the page on its own line. If `false` the math will be rendered in inline mode. (default: `false`)
+- `output`: `string`. Determines the markup language of the output. The valid choices are:
+ - `html`: Outputs KaTeX in HTML only.
+ - `mathml`: Outputs KaTeX in MathML only.
+ - `htmlAndMathml`: Outputs HTML for visual rendering and includes MathML for accessibility. This is the default.
+- `leqno`: `boolean`. If `true`, display math has `\tag`s rendered on the left instead of the right, like `\usepackage[leqno]{amsmath}` in LaTeX.
+- `fleqn`: `boolean`. If `true`, display math renders flush left with a `2em` left margin, like `\documentclass[fleqn]` in LaTeX with the `amsmath` package.
+- `throwOnError`: `boolean`. If `true` (the default), KaTeX will throw a `ParseError` when it encounters an unsupported command or invalid LaTeX. If `false`, KaTeX will render unsupported commands as text, and render invalid LaTeX as its source code with hover text giving the error, in the color given by `errorColor`.
+- `errorColor`: `string`. A color string given in the format `"#XXX"` or `"#XXXXXX"`. This option determines the color that unsupported commands and invalid LaTeX are rendered in when `throwOnError` is set to `false`. (default: `#cc0000`)
+- `macros`: `object`. A collection of custom macros. Each macro is a property with a name like `\name` (written `"\\name"` in JavaScript) which maps to a string that describes the expansion of the macro, or a function that accepts an instance of `MacroExpander` as first argument and returns the expansion as a string. `MacroExpander` is an internal API and subject to non-backwards compatible changes. See [`src/macros.js`](https://github.com/KaTeX/KaTeX/blob/master/src/macros.js) for its usage. Single-character keys can also be included in which case the character will be redefined as the given macro (similar to TeX active characters). *This object will be modified* if the LaTeX code defines its own macros via `\gdef`, which enables consecutive calls to KaTeX to share state.
+- `minRuleThickness`: `number`. Specifies a minimum thickness, in ems, for fraction lines, `\sqrt` top lines, `{array}` vertical lines, `\hline`, `\hdashline`, `\underline`, `\overline`, and the borders of `\fbox`, `\boxed`, and `\fcolorbox`. The usual value for these items is `0.04`, so for `minRuleThickness` to be effective it should probably take a value slightly above `0.04`, say `0.05` or `0.06`. Negative values will be ignored.
+- `colorIsTextColor`: `boolean`. In early versions of both KaTeX (<0.8.0) and MathJax, the `\color` function expected the content to be a function argument, as in `\color{blue}{hello}`. In current KaTeX, `\color` is a switch, as in `\color{blue} hello`. This matches LaTeX behavior. If you want the old `\color` behavior, set option `colorIsTextColor` to true.
+- `maxSize`: `number`. All user-specified sizes, e.g. in `\rule{500em}{500em}`, will be capped to `maxSize` ems. If set to `Infinity` (the default), users can make elements and spaces arbitrarily large.
+- `maxExpand`: `number`. Limit the number of macro expansions to the specified number, to prevent e.g. infinite macro loops. If set to `Infinity`, the macro expander will try to fully expand as in LaTeX. (default: 1000)
+- `strict`: `boolean` or `string` or `function` (default: `"warn"`). If `false` or `"ignore`", allow features that make writing LaTeX convenient but are not actually supported by (Xe)LaTeX (similar to MathJax). If `true` or `"error"` (LaTeX faithfulness mode), throw an error for any such transgressions. If `"warn"` (the default), warn about such behavior via `console.warn`. Provide a custom function `handler(errorCode, errorMsg, token)` to customize behavior depending on the type of transgression (summarized by the string code `errorCode` and detailed in `errorMsg`); this function can also return `"ignore"`, `"error"`, or `"warn"` to use a built-in behavior. A list of such features and their `errorCode`s:
+
+ - `"unknownSymbol"`: Use of unknown Unicode symbol, which will likely also
+ lead to warnings about missing character metrics, and layouts may be
+ incorrect (especially in terms of vertical heights).
+ - `"unicodeTextInMathMode"`: Use of Unicode text characters in math mode.
+ - `"mathVsTextUnits"`: Mismatch of math vs. text commands and units/mode.
+ - `"commentAtEnd"`: Use of `%` comment without a terminating newline.
+ LaTeX would thereby comment out the end of math mode (e.g. `$`),
+ causing an error.
+ - `"htmlExtension"`: Use of HTML extension (`\html`-prefixed) commands,
+ which are provieded for HTML manipulation.
+
+ A second category of `errorCode`s never throw errors, but their strictness
+ affects the behavior of KaTeX:
+
+ - `"newLineInDisplayMode"`: Use of `\\` or `\newline` in display mode
+ (outside an array/tabular environment). In strict mode, no line break
+ results, as in LaTeX.
+
+- `trust`: `boolean` or `function` (default: `false`). If `false` (do not trust input), prevent any commands like `\includegraphics` that could enable adverse behavior, rendering them instead in `errorColor`. If `true` (trust input), allow all such commands. Provide a custom function `handler(context)` to customize behavior depending on the context (command, arguments e.g. a URL, etc.). A list of possible contexts:
+
+ - `{command: "\\url", url, protocol}`
+ - `{command: "\\href", url, protocol}`
+ - `{command: "\\includegraphics", url, protocol}`
+ - `{command: "\\htmlClass", class}`
+ - `{command: "\\htmlId", id}`
+ - `{command: "\\htmlStyle", style}`
+ - `{command: "\\htmlData", attributes}`
+
+ Here are some sample trust settings:
+
+ - Forbid specific command: `trust: (context) => context.command !== '\\includegraphics'`
+ - Allow specific command: `trust: (context) => context.command === '\\url'`
+ - Allow multiple specific commands: `trust: (context) => ['\\url', '\\href'].includes(context.command)`
+ - Allow all commands with a specific protocol: `trust: (context) => context.protocol === 'http'`
+ - Allow all commands with specific protocols: `trust: (context) => ['http', 'https', '_relative'].includes(context.protocol)`
+ - Allow all commands but forbid specific protocol: `trust: (context) => context.protocol !== 'file'`
+ - Allow certain commands with specific protocols: `trust: (context) => ['\\url', '\\href'].includes(context.command) && ['http', 'https', '_relative'].includes(context.protocol)`
+- `globalGroup`: `boolean` (default: `false`). Place KaTeX code in the global group. As a consequence, `\def` and `\newcommand` persist in `macros` across render calls. In LaTeX, constructs such as `\begin{equation}` and `$$` create a local group and prevent definitions from becoming visible outside of those blocks.
+
+For example:
+
+```js
+katex.render("c = \\pm\\sqrt{a^2 + b^2}\\in\\RR", element, {
+ displayMode: true,
+ macros: {
+ "\\RR": "\\mathbb{R}"
+ }
+});
+```

+#### Other KaTeX Environments
+
+| Environments | How they differ from those shown above |
+|:-----------------------------------------------|:------------------|
+| `darray`, `dcases`, `drcases` | … apply `displaystyle` |
+| `matrix*`, `pmatrix*`, `bmatrix*` `Bmatrix*`, `vmatrix*`, `Vmatrix*` | … take an optional argument to set column alignment, as in `\begin{matrix*}[r]`
+| `equation*`, `gather*` `align*`, `alignat*` | … have no automatic numbering. |
+| `gathered`, `aligned`, `alignedat` | … do not need to be in display mode. … have no automatic numbering. … must be inside math delimiters in order to be rendered by the auto-render extension. |
+
+
+
+Acceptable line separators include: `\\`, `\cr`, `\\[distance]`, and `\cr[distance]`. *Distance* can be written with any of the [KaTeX units](#units).
+
+The `{array}` environment supports `|` and `:` vertical separators.
+
+The `{array}` environment does not yet support `\cline` or `\multicolumn`.
+
+`\tag` can not yet be applied to individual environment rows.
+
+
+
+**Unicode**
+
+The letters listed above will render properly in any KaTeX rendering mode.
+
+In addition, Armenian, Brahmic, Georgian, Chinese, Japanese, and Korean glyphs are always accepted in text mode. However, these glyphs will be rendered from system fonts (not KaTeX-supplied fonts) so their typography may clash.
+You can provide rules for CSS classes `.latin_fallback`, `.cyrillic_fallback`, `.brahmic_fallback`, `.georgian_fallback`, `.cjk_fallback`, and `.hangul_fallback` to provide fallback fonts for these languages.
+Use of these glyphs may cause small vertical alignment issues: KaTeX has detailed metrics for listed symbols and most Latin, Greek, and Cyrillic letters, but other accepted glyphs are treated as if they are each as tall as the letter M in the current KaTeX font.
+
+If the KaTeX rendering mode is set to `strict: false` or `strict: "warn"` (default), then KaTeX will accept all Unicode letters in both text and math mode.
+All unrecognized characters will be treated as if they appeared in text mode, and are subject to the same issues of using system fonts and possibly using incorrect vertical alignment.
+
+For Persian composite characters, a user-supplied [plug-in](https://github.com/HosseinAgha/persian-katex-plugin) is under development.
+
+Any character can be written with the `\char` function and the Unicode code in hex. For example `\char"263a` will render as $\char"263a$.

+
+### Line Breaks
+
+KaTeX 0.10.0+ will insert automatic line breaks in inline math after relations or binary operators such as “=” or “+”. These can be suppressed by `\nobreak` or by placing math inside a pair of braces, as in `{F=ma}`. `\allowbreak` will allow automatic line breaks at locations other than relations or operators.
+
+Hard line breaks are `\\` and `\newline`.
+
+In display math, KaTeX does not insert automatic line breaks. It ignores display math hard line breaks when rendering option `strict: true`.

+
+**Notes:**
+
+`distance` will accept any of the [KaTeX units](#units).
+
+`\kern`, `\mkern`, `\mskip`, and `\hspace` accept unbraced distances, as in: `\kern1em`.
+
+`\mkern` and `\mskip` will not work in text mode and both will write a console warning for any unit except `mu`.
+
+
+
+| KaTeX Unit | Value | KaTeX Unit | Value |
+|:---|:---------------------|:---|:----------------|
+| em | CSS em | bp | 1/72 inch × F × G|
+| ex | CSS ex | pc | 12 KaTeX pt|
+| mu | 1/18 CSS em | dd | 1238/1157 KaTeX pt |
+| pt | 1/72.27 inch × F × G | cc | 14856/1157 KaTeX pt |
+| mm | 1 mm × F × G | nd | 685/642 KaTeX pt |
+| cm | 1 cm × F × G | nc | 1370/107 KaTeX pt|
+| in | 1 inch × F × G | sp | 1/65536 KaTeX pt |
+
+
+
+where:
+
+
+
+F = (font size of surrounding HTML text)/(10 pt)
+
+G = 1.21 by default, because KaTeX font-size is normally 1.21 × the surrounding font size. This value [can be overridden](font.md#font-size-and-lengths) by the CSS of an HTML page.
