Issue with 100VH display *Please help uwu

Hello everyone!
I’m having an issue with my homepage height, I would like it to be 100vh in every computer. The problem is I have 3 elements in there: the top marquee, a middle section with content, and a logo strip on the bottom. The marquee has a height of 60 px and the logo strip is 100 px. I dont know how much the middle section measures but the goal is to display the three elements in the entire viewport. Right now you have to scroll down a bit to be able to notice the brand logos.
Thank you so much in advance and sorry if this question is a bit basic but I haven’t been able to find the answer.
