A card is an interface element that is great for distinguishing information and actions. Use it to highlight primary user tasks, business goals, or other actionable tasks.
This replaces a panel.
Use the Card Header field to position text above the card content, similar to the Panel in Bootstrap 3.
The body of the card can include any HTML, including links. Submit a support request if you have any questions about Cards.

Do: Use cards in the right sidebar for fixed information such as quick contact information, hours, and more.
Don't: Use more cards than are necessary. If you have two action items, use two cards.
Don't: Present more than one primary action per card.
