3-column preview card component solution

Hello 👋,

This is my solution for the 3-column preview card component challenge. 👨‍💻

I'm looking for help with positioning the footer. On the desktop site I used .sticky-footer { position: sticky; top: 95%; } and on mobile .sticky-footer { display: none; }. I know this isn't correct but if I don't use display: none; the footer shows within the div and not below the content.

Thank you for taking the time to view my solution, and for any feedback provided!
