-Slides are contained within a limited portion of the screen by default to allow them to fit any display and scale uniformly.

Four different types of backgrounds are supported: color, image, video and iframe. Below are a few examples.

You can apply full page backgrounds outside of the slide area by adding a ```data-background``` attribute to your ```<section>``` elements. Four different types of backgrounds are supported: color, image, video and iframe.
+##### Color Backgrounds
+All CSS color formats are supported, like rgba() or hsl().
```html
-<section data-background="#ff0000">
- <h2>All CSS color formats are supported, like rgba() or hsl().</h2>
+<section data-background-color="#ff0000">
+ <h2>Color</h2>
</section>
-<section data-background="http://example.com/image.png">
- <h2>This slide will have a full-size background image.</h2>
+```
+
+##### Image Backgrounds
+By default, background images are resized to cover the full page. Available options:
+
+| Attribute | Default | Description |
+| :--------------------------- | :--------- | :---------- |
+| data-background-image | | URL of the image to show. GIFs restart when the slide opens. |
+| data-background-size | cover | See [background-size](https://developer.mozilla.org/docs/Web/CSS/background-size) on MDN. |
+| data-background-position | center | See [background-position](https://developer.mozilla.org/docs/Web/CSS/background-position) on MDN. |
+| data-background-repeat | no-repeat | See [background-repeat](https://developer.mozilla.org/docs/Web/CSS/background-repeat) on MDN. |
+```html

+ <h2>This background image will be sized to 100px and repeated</h2>
</section>
+```
+
+##### Video Backgrounds
+Automatically plays a full size video behind the slide.
+
+| Attribute | Default | Description |
+| :--------------------------- | :------ | :---------- |
+| data-background-video | | A single video source, or a comma separated list of video sources. |
+| data-background-video-loop | false | Flags if the video should play repeatedly. |
+| data-background-video-muted | false | Flags if the audio should be muted. |
+
+```html
<section data-background-video="https://s3.amazonaws.com/static.slid.es/site/homepage/v1/homepage-video-editor.mp4,https://s3.amazonaws.com/static.slid.es/site/homepage/v1/homepage-video-editor.webm" data-background-video-loop data-background-video-muted>
- <h2>Video. Multiple sources can be defined using a comma separated list. Video will loop when the data-background-video-loop attribute is provided and can be muted with the data-background-video-muted attribute.</h2>
+ <h2>Video</h2>
</section>
+```
+
+##### Iframe Backgrounds
+Embeds a web page as a background. Note that since the iframe is in the background layer, behind your slides, it is not possible to interact with the embedded page.
+```html
<section data-background-iframe="https://slides.com">
- <h2>Embeds a web page as a background. Note that the page won't be interactive.</h2>
+ <h2>Iframe</h2>
</section>
```
+##### Background Transitions
Backgrounds transition using a fade animation by default. This can be changed to a linear sliding transition by passing ```backgroundTransition: 'slide'``` to the ```Reveal.initialize()``` call. Alternatively you can set ```data-background-transition``` on any section with a background to override that specific transition.

This triggers the default index HTML to load the PDF print stylesheet ([css/print/pdf.css](https://github.com/hakimel/reveal.js/blob/master/css/print/pdf.css)). You can test this with [lab.hakim.se/reveal-js?print-pdf](http://lab.hakim.se/reveal-js?print-pdf).
+Export dimensions are inferred from the configured [presentation size](#presentation-size). Slides that are too tall to fit within a single page will expand onto multiple pages. You can limit how many pages a slide may expand onto using the `pdfMaxPagesPerSlide` config option, for example `Reveal.configure({ pdfMaxPagesPerSlide: 1 })` ensures that no slide ever grows to more than one printed page.
