Customize Theme

$ curl http://localhost:3000/revealjs/css/theme/black.css > original.css

Edit original.css, And then run revealgo with --theme option:

$ revealgo --theme original.css slide.md

Get the default slide HTML file:

$ curl http://localhost:3000/ > slide.html

Edit slide.html, and then open http://localhost:3000/slide.html with your browser. A slide with the modified configurations will come up.

Using slide multiplex

The multiplex plugin allows your audience to follow the slides of the presentation you are controlling on their own phone, tablet or laptop

--- reveal.js site

When --multiplex is enabled, the client slides can be found on the / path and the master ones under /master/. The master presentation will push its changes to all the client ones for every transition, is like having a remote control!

For example, your laptop's IP address in the local network is 192.168.100.10 and you are using the port 3000, so your audience should see the slides on http://192.168.100.10:3000/, and you should be able to control their slides through http://192.168.100.10:3000/master/.

NOTE: Bear in mind multiplex feature will not work as expected when 1) the presenter computer firewall denies incomig traffic or 2) the local network does not allow traffic between devices on the port you picked
