[Screenshot of white space under div]

I can’t work out why this white space is visible, I am a newbie to coding and would greatly appreciate any help possible. I have tried googling the answer but have had no luck!
body{ background: rgb(245,245,245); color: green; font-size: 25px; font-family: Helvetica; margin: 0; padding: 0; outline: none; border: 0; display: flex; } .card { font-weight: lighter; text-align: center; color: white; background: rgb(50, 50, 50); margin: 0; padding: 20px; }<html>

I dont have all your code, but I think it is because you have an h2 tag in the first card-section and then a h3 in the next. Try and change to both h2 or h3 and see if the whitespace dissapears.
You can use the piece of code above.
I hope my answer will help you.
