# Combined Configurations¶

MathJax comes with a number of pre-defined and pre-compiled configuration files in the MathJax/config directory. The default.js file contains nearly all the possible configuration options together with comments explaining them, so you can use that file to customize MathJax to your needs. Simply load it via

<script type="text/javascript" src="path-to-MathJax/MathJax.js?config=default"></script>


where path-to-MathJax is the URL to the MathJax directory on your server or hard disk. If you are using MathJax from a CDN, you can view the contents of default.js as a reference, but you will not be able to edit the CDN copy. It is possible to use the CDN copy of MathJax with your own configuration file, however; see Using a Local Configuration File with the CDN for details.

The remaining files in the MathJax/config directory are combined configuration files that include not just configuration parameters but also the files that MathJax would need to load for those configurations; you can browse the directory on Github. Using one of these means MathJax will have to load fewer files, and since each file access requires establishing connections over the network, it can be faster to load one larger file than several smaller ones. See Loading and Configuring MathJax for more details about how to load configurations, and how to modify the parameters for a configuration file.

The following sections describe the contents of the combined configuration files. Each comes in two flavors: a standard version and a “full” version. The standard version simply defines the output processor(s) that are part of the configuration, but doesn’t load the code that implements the output processor. The full version loads the complete output processors, so everything that MathJax needs for the page should be loaded up front, and there will be no delay once the page is ready to be processed. To obtain the “full” version, add -full to the end of the configuration file name.

## The TeX-MML-AM_CHTML configuration file¶

This configuration file is one of the most general of the pre-defined configurations. It loads all the main MathJax components, including the TeX, MathML, and AsciiMath preprocessors and input processors, the AMSmath, AMSsymbols, noErrors, and noUndefined TeX extensions, the CommonHTML output processor definitions, and the MathMenu and MathZoom extensions. It is equivalent to the following configuration:

MathJax.Hub.Config({
jax: ["input/TeX","input/MathML","input/AsciiMath","output/CommonHTML"],
TeX: {
extensions: ["AMSmath.js","AMSsymbols.js","noErrors.js","noUndefined.js"]
}
});


In addition, it loads the mml Element Jax, the TeX, MathML, and AsciiMath input jax main code (not just the definition files), as well as the toMathML extension, which is used by the Show Source option in the MathJax contextual menu. The -full version also loads the CommonHTML output jax main code, plus the CommonHTML mtable extension, which is normally loaded on demand.

See the tex2jax configuration section for other configuration options for the tex2jax preprocessor, and the TeX input jax configuration section for options that control the TeX input processor.

## The Accessible configuration file [Deprecated]¶

This configuration file is essentially the same as TeX-AMS-MML_HTMLorMML except that it includes options that are designed for assistive technology, particularly for those with visual challenges.

Warning

This file is deprecated since the controls that make MathJax work with screen readers are now available in the MathJax contextual menu and the AssistiveMML extension, and so there is no need to set them in the configuration file any longer. So you can use any of the other pre-defined configurations and readers with special needs should be able to change the MathJax settings themselves to be appropriate for their software.

The Accessible configuration is equivalent to the following:

MathJax.Hub.Config({
config: ["MMLorHTML.js"],
jax: ["input/TeX","input/MathML","output/HTML-CSS","output/NativeMML", "output/PreviewHTML"],
TeX: {
extensions: ["AMSmath.js","AMSsymbols.js","noErrors.js","noUndefined.js"]
},

In addition, it loads the mml Element Jax, the TeX and MathML input jax main code (not just the definition files), as well as the toMathML extension, which is used by the Show Source option in the MathJax contextual menu. The -full version also loads the HTML-CSS, CommomHTML, and NativeMML output jax main code, plus the HTML-CSS mtable extension, which is normally loaded on demand.
