Problem with design topics

Hi guys,

I hope you are doing well!

I am currently facing two problems that I just can’t fix; tried many ways:

  1. My site is supposed to reach an end with the finish of the last image. This works well with the desktop view, but on mobile, the site just does not finish at the right point - see screenshots attached.
  2. Between “Section 4th” and “Section 5th” I created some space (margin: 400 on bottom of “Section 4th”) to make the transition process related to the interaction effects I implemented more natural. Again, it works well on desktop, but does not work on mobile, as during this transitional stage, a sudden increase in speed happens (I do not know why; it should just continue fluently).

Can you help me out here, please?
