You look through HyperCard’s windows onto one card from a stack. You can only see one card at a time in a window, although the stack you are examining can hold hundreds of cards. Cards hold HyperCard’s text, graphics, and animations. The hardest thing to understand about a card is that it is composed of two layers. Click on the leftmost button to learn about these layers, and then click on the other buttons to learn more about cards.
