3-column-preview-card-component

Hey Aleksandra! It looks great!... Here are some suggestions:

• Document should have one main landmark, Contain the component with <main>.
• I recommend using align-items: flex-start; in the .container for a better visualization in the mobile version.

I hope this is helpful to you... Keep it up👍

you can write button:hover{bg-color:trasparent}, so the background will be the same as the parent, insted of repeating yourself for every signle card.
