|
* MathJax/config/MMLorHTML.js
|
|
*
|
|
* Chooses between the NativeMML and HTML-CSS output jax depending
|
|
* on the capabilities of the browser and configuration settings
|
|
* of the page.
|
|
*
|
|
* This file should be added to the config array when configuring
|
|
* MathJax. Note that if you include this, you should NOT include
|
|
* an output jax in the jax array (it will be added for you by
|
|
* this file).
|
|
*
|
|
* You can specify the preferred output jax on a global or
|
|
* browser-by-browser basis. To specify it globally, use
|
|
*
|
|
* MathJax.Hub.Config({
|
|
* MMLorHTML: {prefer: "MML"} // or "HTML"
|
|
* });
|
|
*
|
|
* To specify on a browser-by-borwser basis, use
|
|
*
|
|
* MathJax.Hub.Config({
|
|
* MMLorHTML: {prefer: {
|
|
* MSIE: "MML",
|
|
* Firefox: "MML",
|
|
* Opera: "HTML",
|
|
* other: "HTML"
|
|
* }}
