Fylo Landing Page With Two Columns Layout Master

Hello, Frontend Mentor community. This is my challenge for the 'Fylo Landing Page With Two Columns Layout."

Since they weren't provided with the challenge I made my own social icons. However, I couldn't figure out how to do their hover effect. I also couldn't make the "check your email message" on the inputs. Lastly, I also couldn't figure out how to do hover on the green <a> tag since it's supposed also to cover the arrow icon.

I'd be happy to get so feedback and tips on getting those working properly, so I can learn and update the code.
