Huddle Landing Page

Hi, struggled a bit with positioning and spacing everything out to look like the original design on desktop (still not perfect). I think my CSS is a bit redundant and would love some feedback on how to layout everything a bit better and with less code if possible. The icons especially i couldn't get to lay on the bottom right of the page so I'd love to know how to do that because playing with margins and padding wasn't working for me. Thank you!
