Responsive Landing page

Hello guys, I have given a try to a CSS framework which is Tailwind please do review the challenge and give your feedbacks on what changes can be made. I found it difficult to place the early access box in the responsive manner it keeps on changing its position again and again in the mobile version of code its particular to only one size of mobile screen if the screen size changes the box movies from the position and disturbs the design. I will be happy to know how to solve this problem.
