RelativeNumber

for Reveal.js

This simple plugin checks if there already is an element with the class "slide-number" in the presentation. If so, it moves the slidenumber there.

Create an empty element with class "slide-number" in your document. For example, in a menubar like above.

Now you can style it and make it fit in your content. For example, give it a relative position.

For the menu you might use my simplemenu plugin.
