Frontend-Mentor-3-column-preview-card-component

Hello there! Nice job on completing this project. Viewing your solution you did well implementing the code. I think you should considered the following as well...

• Add margin-top: 7rem; inside the container rule set to align the content in the center
• Inside the main article add a height of 400px
• Add a top margin inside the rule set of main article .btn make it margin-top: 6rem;
• Wrap the attribution with footer tag and add a padding at least 1rem to have spaces in between

Hope this is helpful and Keep going!
