Testimonials Grid Challenge

Hi, I implemented CSS Grid in the following way:

1. Designed for the Mobile first as per design requirements.
2. In between the Mobile and the Desktop design I add the following code: grid-template-columns: repeat(auto-fit, minmax(327px, 0.75fr)) so as to adapt to the screen viewport width.
3. Designed for the Desktop as per design requirements; placing the grid items explicitly and then using the CSS transform property to achieve the desired look.

Please let me know, if my approach was correct! Thanks in advance!
