i'm trying to figure out how to work this;
The element now has an id of thumbnail. With this selector, use the example CSS values above to place a box-shadow on the card.

this is the css values;
box-shadow: 0 10px 20px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);

and this is the code i used;
.thumbnail {
box-shadow: 0 10px 20px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);
but it's mot working on the fcc site.
