Four Card Responsive

Hello Facundo 👋 Congratulations for completing this challenge 🎉 I see you make good use of grid box and calculate the row and column nicely👍

Some of my suggestions below:

• I see you have imported the font family Poppins but I couldn't see you are using it. font-family: 'Poppins', sans-serif; So you might not be intentionally not using the given font, right?
• I see you put the first part of heading into <span>. It should be part of the heading so is semantically better to put it into h1 as well and add necessary <strong> and line break. And <span> is an inline element so be careful your using might cause some unwanted inline effect.
• Incorrect icon in Calculator card.

Hope this helps! Have a nice day!
