Hello
To amend you can add the following to the Custom CSS field of your templates parameters (Extensions -> Templates -> [YourTemplateStyle] -> Custom CSS)....
.owl-item .item {
box-shadow: 0 0 5px rgba(0,0,0,.3);
background-color: white;
}
.owl-item .item h2 + h2 {
padding: 0 15px;
}
.owl-item .item h2 + p {
padding: 0 15px;
}
.owl-item .btn {
display: block;
margin: 0;
}
