Challenge: Add a box-shadow to a Card-like Element

Link to the challenge:

Your code:

.thumbnail id {
box-shadow:0 10px 20px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);
}

What the challenge asks:

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.

In your style element, to target an id you have to use a # plus the id name (like #example) so, your CSS selector must be #thumbnail { ... } instead of what you have .thumbnail id { ... }.
