### Stretching elements
Sometimes it's desirable to have an element, like an image or video, stretch to consume as much space as possible within a given slide. This can be done by adding the ```.stretch``` class to an element as seen below:
```html
<section>
<h2>This video will use up the remaining space on the slide</h2>
<video class="stretch" src="http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"></video>
</section>
```
Limitations:
- Only direct descendants of a slide section can be stretched
- Only one descendant per slide section can be stretched

## MathJax
If you want to display math equations in your presentation you can easily do so by including this plugin. The plugin is a very thin wrapper around the [MathJax](http://www.mathjax.org/) library. To use it you'll need to include it as a reveal.js dependency, [find our more about dependencies here](#dependencies).
The plugin defaults to using [LaTeX](http://en.wikipedia.org/wiki/LaTeX) but that can be adjusted through the ```math``` configuration object. Note that MathJax is loaded from a remote server. If you want to use it offline you'll need to download a copy of the library and adjust the ```mathjax``` configuration value.
Below is an example of how the plugin can be configured. If you don't intend to change these values you do not need to include the ```math``` config object at all.
```js
Reveal.initialize({
// other options ...
math: {
mathjax: 'http://cdn.mathjax.org/mathjax/latest/MathJax.js',
config: 'TeX-AMS_HTML-full' // See http://docs.mathjax.org/en/latest/config-files.html
},
dependencies: [
{ src: 'plugin/math/math.js', async: true }
]
});
```
Read MathJax's documentation if you want [secure delivery](http://docs.mathjax.org/en/latest/start.html#secure-access-to-the-cdn) or serve [specific versons](http://docs.mathjax.org/en/latest/configuration.html#loading-mathjax-from-the-cdn) for stabilty.
