Draggable progress bar slider

Just want to say thanks heaps to Timothy Ricks (https://www.timothyricks.com/), and recognize the awesome talents and generosity for sharing and for showing us how to create this very cool draggable slider -
Draggable Progress Bar Slider - Webflow

I spent ages trying to get something like this to work with a slider but was failing miserably.

So, thanks again Timothy Ricks!
