Box shadow styling tips

I was wondering what settings I’d need to configure a group to have a box shadow to look like these examples:

This is their css respectively:
box-shadow: rgba(149, 157, 165, 0.2) 0px 8px 24px;
box-shadow: rgba(100, 100, 111, 0.2) 0px 7px 29px 0px;

I’m no expert but I have my settings set at Outset, 0, 15, 35, 0, 000000 @20% for a heavy shadow styled card. For a light shadow style I have Outset, 0, 3, 3, 0, 000000 @20%.
To change the shadow styling, I only change the vertical offset and blur radius.
