Buttons can also be use for sound. Once you know how to work with text, graphic and buttons you can start changing your stacks to make them more useful to you. HyperCard stacks can be purchased or created from scratch. Different stacks can have cards of different sizes. You can have more than one stack of cards open on the screen at a time.
All cards have a foreground and a background.
Cards can contain text fields, graphics, and buttons. Go to the Home stack by pressing X-H, click either the HyperCard Tour icon for an introduction, or the Practice icon for exercises using HyperCard. Additional help is available from within HyperCard.
