Responsive Four Card Feature Section - HTML, SASS, Flexbox

Your solution looks very neat! I think that if you try to give the box shadow a little bit more blur you could get a perfect match! This is what I used in mine, still not quite the same but maybe helps you getting there! cheers!

box-shadow: 0 8px 18px 3px rgba(76, 78, 97, 0.13);
