Apply your own class name to your card ( `<div class="myclass">...</div>`)
Then apply `box-shadow` CSS to that class like
```
.myclass {
box-shadow: 0 0 0 1px rgba(0,0,0,.1), 0 0 16px 0 rgba(0,0,0,.05);
}
```
You can use a browser inspect mode to adjust the amount of shadow visually. Chrome and "new edge" have a nice tool for this
Similarly, if you see things you like the best tool at your disposal is the browser's HTML / CSS inspector!
