I've updated my Webflow Codes & Tutorials site with two types of Parallax implementation.
One creates a hero parallax zoom in when you scroll and the other is just a regular parallax scroll.
Title: Hero Parallax – Regular on scroll
Title: Hero Parallax – Zoom in on scroll
Both examples are built around the hero being 100% in height, but that is just optional and (hopefully) easy to change.
As usual it's all covered step by step.
