Responsive Four card feature section using CSS Grid

This is the second solution I am submitting for this challenge! Instead of specifying margin and padding for every element, I used CSS Grid to improve the layout and make it more responsive. It was a little challenging for me while making the responsive layout of the site as I am not used to making such layouts using CSS Grid but I tried my best. I would love to hear your feedback on this and help me improve my code as much as possible. Thank you for your time!

Note - I had to darken the light text due to accessibility issues (contrast error)
