A material design card. A card is an elevated layer, used to visually group content.
The following example shows a card with some content.
property Color color: #white
property Float radius: 2
The background color and card radius.
Clipping is enabled by default on cards, so content will be clipped to its bounds and radius.
property Bool activatable: false
When a card is activatable, it will elevate slightly and emit the activated() event when tapped.
