3-column-preview-card-component-main (responsive)

Hey khshakib, good job on completing this challenge. Keep up the good work

Your solution looks good however I think in comparison with the design that each section of the container needs some padding around the content.

In terms of accessibility issues simply wrap all your content between <main> tags and the issues should be fixed

In terms of your validation errors, I recommend reading the css docs on media queries to get the latest code.

I hope this helps

Cheers Happy coding 👍
