Hello world, I work today on a problem when we generate a presentation with DeckJS, the font size is very small on projection.
I've find an issue for this, and you need to create a template with all deckJS dependancies, and an other css file to change some rules. To change the font-size of a body slide (not title or subtitle), you need to rewrite this rules like this : .deck-slide-scaler p { font-size: 64px } The scaling always works, and you don't need to touch the deckjs files.
