Mozilla branded theme for reveal.js based on light blue/grey Firefox colors found at:
http://www.mozilla.org/en-US/styleguide/identity/firefox/color/
You can manually use the theme by placing the style sheet into the <revealjs>/css/theme/ directory. Then in your reveal.js index.html file, update your theme style sheet call to:
<link rel="stylesheet" href="css/theme/mozilla.css" id="theme">
By default there are no borders around images. This was designed for logos with transparent backgrounds (such as Firefox or Marketplace) to look their best. If you want to have a border around your image, just call the img_border class:
<img src="img/superAwesomeImageYo.png" class="img_border" />
