Single price grid component

Great work on this Pedro! Nice to see you using min-width media queries and working mobile-first too 👍

Here are a couple of things I picked up from looking at your code:

• In your HTML you have 3 h4 elements, but no other headings. I would always recommend starting at h1 and working down depending on the content hierarchy. This makes sure that the content outline for screen reader users is well structured.
• I would also recommend not using IDs for styling purposes. Their specificity is really high and also they can't be reused on the same page. I always stick with classes, pseudo selectors, attribute selectors, and type selectors. It makes your CSS far more maintainable as it grows.

I hope these pointers help. Keep up the great work! 🙂
