After coming across this interesting example, I started pondering whether it could be replicated using javascript and CSS. Essentially, what caught my eye was a text with an experimental text-stroke CSS property that appeared to have a unique effect when the user scrolled past it - almost like a filled css-mask type of effect.

I'm really keen on learning how to achieve this effect myself. I don't necessarily need all the technical details, just a simple explanation of how they managed to create such a neat effect. Can anyone shed some light on this?
