Reverse scrolling - Where to place JS/HTML/CSS code


I would like to create something out of the ordinary. :grimacing: A homepage that starts at the bottom and that navigates bottom-to-top, so ‘reverse scrolling’. I have found the JS/HTML/CSS solution for this, link:

Could you please explain me how and where to integrate this JS/HTML/CSS code so that the homepage starts at the bottom, and scrolls to the top?

PS. I have not added a Read-Only link because I’m at the very beginning of my first project at Webflow.

Thank you very much in advance for your response :pray:t4:
