Questions

I was wondering if someone has a way of setting the images centered without messing up the card view, when not expanded the image goes all the way to the left on iPad view. someone has a fix for this?

try this wee bit of CSS in your app.css file

.card-expandable {
width: 90%;
margin: 25px auto;
}
