Anyone else still using and enjoying bootstrap for new projects?
Tailwind is neat but the lack of component class names means you have to roll your own or embed very specific style classes like shadows, borders, etc in to every component.
I did some research and discovered the Intersection Observer API, which seemed like a perfect fit for this use case. I hacked up a basic implementation[1], asked for some feedback, and promptly forgot about it. I was super stoked to see someone else pick up the idea and run with it, doing a much better job than I could have. Open source is fun!
