Minimalistic slides

Thursday, April 11, 2024 6:41 PM

Because I can't do something without doing something else first (Carl Sagan¹ said something about that).

I first have to write presentation software before I can create slides.

The key tricks here are:

using flex box to put slides side-by-side
using scroll snap to snap a slide
the keyboard navigation (using cursor keys ◀ and ▶) works because of the tabindex and autofocus attributes

AFAIK the slide speed cannot be set and even worse: it differs from browser to browser (slow in Chrome, fast in Firefox).
