Make the cards stand out more from the background

[davefoord]

Is it worth making the draggable cards slightly more distinct - I have done this by adding some CSS to give the cards a thin grey border, but not everyone will have the ability or know-how to do this.

This was the CSS that I personally added to my site:

/Adds a border around the cards in the preference sorting activity/
li.d-flex.card.p-3.mb-2.optionitem.draggable {
border-style: solid;
border-color: #c0c0c0;
border-width: thin;
}
