@ajk9044 - If you want to know how some Webflow animations are created you can use developer tools and inspect the project js file. First find the value of the elements data-w-id in the DOM and then search the JS file for that value. That will show you the JSON that controls the animation handled by the IX2 library used by Webflow. It is pretty easy to read but can take you some time to determine the whole animation.
Effectively this in this case this is really an accordion effect on .project-wrapper elements controlled by scroll. If you can’t build this stuff yourself you can always hire someone who can.
