How do I Integrate a Jump Link Like This?

Hi Everyone! I’m currently working on my portfolio and would like to integrate jump links. I found a style that I really like but am not sure how to build it out on Webflow. Would something like this be possible?

In this version, you can scroll until you get to the process bar. Once you pass that, it would stick to the top of the page at a smaller scale and change color after jumping/scrolling into each section. Any feedback is greatly appreciated!
