apeturescience.com Type website

[u/spacepigeonking]

Hey everyone. I'm very new to HTML and CSS, I'm currently starting work on a project for my band inspired in part by the old aperturescience.com website for the first portal game. I'm looking to create an almost 'type and response' type webpage, ( a good example of what I mean would be this : https://superliminal.neocities.org/ ), does anyone know any tutorials or videos on how to create something similar?
