Pod Request Access Landing Page (Vanillia CSS)

What specific areas of your project would you like help with?

Positioning - this is something I have trouble with in a lot of projects. I don't feel like I did it correctly, and that I kind of just threw something together and got lucky that it works. Plus, at anything larger than my screen size it is going to break

In this project, I used position rel/abs a lot and did a majority of the placement using percentages with the top/bottom/left/right properties. I had to use a bunch of media queries and on screens larger than my own it's going to break (as I'd need more media queries). Would someone be able to explain a more correct way to do this and possibly send me a link to another solution that did good at placing the different items correctly (or a video that goes in-depth on it)?

Edit: As you can see in FM's screenshot, the placement of the main div is off

Thank you!
