Although personally PowerPoint It has always seemed like a useless bullshit with its transition effects, there are people who like to make presentations with scrolling text and similar things.
Through a friend I have discovered deck.js, a bookstore JavaScript that allows us to create modest (but beautiful) presentations that we can show to all our friends or clients, just by having a web browser.
Depends on jQuery y Modernize for purposes and is available under a dual license MIT / GPL. Works on IE7 +, Opera, Chrome, Firefox y Safari. You can see the examples in this link.
Well, you just reminded me that I have to consult something with your partner for my high school PowerPoint hahaha by the way I can fuck him for a while.
The program is not very professional (PowerPoint) but it is not bad.
The good thing is that this one that you show us exempts us from the installation
Good JavaScript library to make excellent presentations in HTML as similar and pleasant as in Power Point. Very easy to understand and use, I recommend it if you want to share a presentation that is accessible with the only requirement of a responsible browser.
Regards!
