My CSS content keeps moving vertically on my website?

Question

So basically I am trying to make a search engine page. The hr does not want to align in the center. On top of that when I resize the page in height it sends the text in the middle and the search bar diagonally left. I am unsure what I am doing wrong. I find positioning in CSS so so hard.

I am unsure on if I am positioning correctly. I was trying to lock my content down by using vh and vw. However I have a lot of trouble locking everything down vertically.
