Changes:

• Fixed the page stacking animation
• Changed the layout of hero section.
• Made navbar position fixed

I was trying to make the navbar sticky which wasn’t working at first and was so annoying, after solving that I found out that it won’t go outside hero section. I was frustrated that I was messing up something so easy. Also it seems that I was doing the stacking animation the wrong way so I fixed that also. So now I have a clean stacking page animation and a navbar that stays at a fixed position.
