First Frontend Mentor Project using Basic CSS

I'm still beginer too, but I have some suggestion:

1. try to use responsive page, add @media screen and(max-width: 375px){.card{width: 80%;padding:5%}} , it means this code is executed when shown iresolution =<375.
2. add margin-top instead of just using margin: auto (you could combine them both) to add more space above card.
3. in mobile responsive try to avoid using font with vh, because smaller the screen, it will less visible to read. sorry I still don't know much, but let's learn together and happy coding :)
