[Support request] How to Create a Box Shadow

Hey Guys,

I’m using your Version 1.0-beta.2 version of Wp Show Posts, currently with the Base Cards.

How would I create a bax shadow around them?

I’ve tried the following code:

.wp-show-posts-columns#wpsp-120 .wp-show-posts-inner {
margin: 0 0 2em 2em;
box-shadow: 0px 2px 16px 0px rgba(0,0,0,.1);
}

But that didn’t work.

Any Ideas?

Thanks
