When creating slides for my talks I use Reveal.js, which allows me to create slides using HTML. These are my general notes about creating presentations this way.
Persistent Header Reveal.js
I use Reveal.js when creating slides for my presentations. Often I want persistent elements on all of the slides (for example my twitter handle @salcode or the conference hash tag). I’ve found the easiest way to do this is by adding a little bit markup and custom CSS.
Full Screen Image in Reveal.js
I like to use Reveal.js for building my slide decks. Getting an image to display full-screen (while avoiding the image being cut-off) can be difficult. The data-background-size attribute provides a solution to this problem.
