Slides for a presentation to colleagues on countering online harassment and abuse. Presentation available online here.
I build my presentations with Reveal.js, a Javascript framework for building web-ready presentations in HTML. Check out the live demo of Reveal.js. I then host them on Github Pages, making them available to users without having to ship Powerpoint files around.

I relied on Chen Hui Jing's excellent tutorial on doing slide decks in Reveal.js to get started.
