The add-on has a top toolbar that\nidentifies the add-on and displays a *card* ---essentially a \"page\" of the\nadd-on's UI. Apps Script represents cards in project code using\n[`Card`](/apps-script/reference/card-service/card) objects.\n\nCard anatomy\n\nA card is a group of UI elements you design. A card consists of the\nfollowing sections:\n\n- **A card header**. This identifies the cards. It has title text, and may optionally have a subtitle and an icon.\n- **One or more card sections** . These are sub-divisions of the card's UI area.\n A section may optionally have a text section header.\n Card sections are separated from each other on the card by a horizontal rule.\n If a card section is particularly large, it is automatically rendered as a\n collapsible section that users can expand or collapse as needed.\n A card can have [no more than 100 card sections](/workspace/add-ons/guides/workspace-restrictions#have_more_than_100_widgets),\n and should have only a few for better performance.\n\n- **Each card section contains one or more UI\n [widgets](/workspace/add-ons/concepts/widgets)** . Widgets provide the user with\n information or interactive controls. Cards and card sections are\n *structural* widgets, so you cannot add those to a card section. A card\n section can have [no more than 100 widgets](/workspace/add-ons/guides/workspace-restrictions#have_more_than_100_widgets),\n and should be as simple as possible for best performance.\n\nYou should design cards around particular user activities or data sets. For\nexample, a Google Workspace add-on that displays data\ntaken from Google Sheets might have a separate card for each sheet it pulls\ndata from.\n\nUsing multiple cards\n\nAdd-ons usually consist of more than one card. You can either configure these\ncards as a simple list for\n[basic navigation with multiple cards](/workspace/add-ons/how-tos/navigation#returning_multiple_cards),\nor configure more complex\n[navigation methods](/workspace/add-ons/how-tos/navigation#navigation_methods)\nto control how the user moves between the cards.\n\nIf the add-on uses basic navigation, when the\nadd-on is first opened the\nGoogle Workspace application it extends constructs a\nlist of the card headers and presents those to the user. Clicking on the card\nheader opens that card. A back arrow is also provided to get back to the card\nheader list. You do not have to code the header and back arrow\nfunctionality---this is done automatically when you define the cards in your\nadd-on.\n\nWhen designing add-ons, it's best to\n[limit the number of cards](/workspace/add-ons/guides/workspace-best-practices#_use_just_a_few_cards)\nyou display at once, since cards must share a limited amount of screen space.\nIt's also best to [avoid unnecessary complexity in cards](/workspace/add-ons/guides/workspace-best-practices#_keep_cards_simple).\n| **Note:** For performance reasons, you can't add more than 100 widgets or 100 card sections to a card."]]
