Made using HTML, CSS basics, Flexbox and mobile-first design

Hey @R0b3rtG, good job on this solution!

Some suggestions for you:

1. Try to split your CSS styles into a different file so it improves the readability and maintainability of your code.
2. You can try to give your main tag a max-width to keep the structure and shape of the card.
3. You can try to follow a CSS naming convention called BEM. You can watch this video for more information Watch the video.
4. You can try to use relative units like em in the future for padding. Here is a link to an article that explains when to use which unit see the article.

I hope this helps, good luck!
