CSS needed for 3 parallaxing functionalities on squarespace site

1. My client would like to replicate this website (www.quinn.pr) initial text parallax over the video on homepage. Copy exactly the movement for the wording overlay on the video and also the text and white space underneath scrolling upwards.

Here is the development link:

2. Consulting Service page:

Please see https://quinn.pr/passionate-people/ to copy functionality of the page exactly.

Fix the text to the left and allow the imagery and accordions to scroll up and down.

3. About page:

Ian Neale section. For the image to stay slower and the text to parallax faster.

Please see: https://www.thebusinessboss.net/ (MEET THE FOUNDER SECTION) for functionality copy.
