Scss Animations and using Intersection Observer API !

Hey, guys!

This is my first time working with intersection observer API. I added these animations to this solution:

1. Navbar changes color after scrolling past a section
2. Images slide in with fade in animations when we enter the viewport.

Still to improve, I need to add:

1. Hamburger menu animations on opening up the menu
2. Better animations for the cards with clip-path(maybe)

Please let me know if any improvement is needed 😁
