4387+Background in reveal.js
4388+-----------------------
4390+Background images can be added to self-contained reveal.js slideshows.
4392+For the same image on every slide, use the reveal.js configuration
4393+option `parallaxBackgroundImage` either in the YAML metadata block
4394+or as a command-line variable. You can also set `parallaxBackgroundHorizontal`
4395+and `parallaxBackgroundVertical` the same way and must also set
4396+`parallaxBackgroundSize` to have your values take effect.
4398+To set an image for a particular slide, add `{data-background-image="/path/to/image"}`
4399+to the first slide-level header on the slide (which may even be empty).
4401+In reveal.js's overview mode, the parallaxBackgroundImage will show up
4402+only on the first slide.
4404+Other background settings also work on individual slides, including
4405+`data-background-size`, `data-background-repeat`, `data-background-color`,
4406+`data-transition`, and `data-transition-speed`.
4408+See the [reveal.js documentation](https://github.com/hakimel/reveal.js#slide-backgrounds)
4416+parallaxBackgroundImage: /path/to/my/background_image.png
4421+Slide 1 has background_image.png as its background.
4423+## {data-background-image="/path/to/special_image.jpg"}
4425+Slide 2 has a special image for its background, even though the header has no content.
