These cards, representing UI pages, are built using the Card service or JSON. Navigation involves pushing new cards onto a stack. Cards can be contextual, appearing in specific host application states, or non-contextual, like homepages, visible in general views. Each card contains sections composed of widgets, offering information or interaction controls. Key actions include defining card navigation, constructing cards with sections and widgets, and implementing actions.\n"],null,["# Card-based interfaces\n\n| **Note:** Google Workspace add-ons are card-based. Editor add-ons are [HTML-based](/workspace/add-ons/concepts/html-interfaces).\n\nGoogle Workspace add-ons present information and user\ncontrols in the sidebar of the\n[host application](/workspace/add-ons/guides/glossary#host_or_host_application)\nUI. An add-on consists of a main identifying toolbar along with one or more\n[cards](/workspace/add-ons/concepts/cards).\n\nEach card represents a particular 'page' of your add-on's UI, and\n[navigating to a new card](/workspace/gmail/add-ons/how-tos/navigation) is\nusually just a matter of creating that card and\n[pushing it onto an internal card stack](/workspace/gmail/add-ons/how-tos/navigation#navigation_methods).\nYou can define navigation flows between cards for a rich interaction experience.\n\nCards can be *non-contextual* or *contextual* . Contextual cards are presented\nto the user when the host application is in a specific context. For example,\nwhen opening a Gmail message or Calendar event. Non-contextual cards (such as\n[homepages](/workspace/add-ons/concepts/homepages)) are presented to the user\noutside of a specific context of the host. For example, when the user is\nviewing their Gmail inbox, main Drive folder, or Calendar.\n\nGoogle Workspace add-ons built in Apps Script use the\n[Card service](/apps-script/reference/card-service/card-service) to create user interfaces out of\n[cards](/workspace/add-ons/concepts/cards). Add-ons built in other languages\nmust return properly formatted JSON for the interface to render as cards.\n\nEach card consists of a header and one or more card sections. Each section is\ncomposed of a set of [widgets](/workspace/add-ons/concepts/widgets). Widgets\ndisplay information to the user or provide interaction controls like buttons.\n\nCard-based interfaces have the following benefits:\n\n- No knowledge of HTML or CSS is needed to create card-based interfaces.\n- Cards and widgets are automatically styled to work well with the Google Workspace applications they extend.\n- Card-based interfaces work on both desktop and mobile devices, but you only\n need to define the interface once.\n\n | **Note:** Gmail is currently the only host application that can be extended by Google Workspace add-ons on mobile.\n\nCreating card-based interfaces\n------------------------------\n\nWhen building card-based add-ons, it's important to understand certain\nconcepts and design patterns. The following guides provide the information\nyou need to build effective card-based add-ons:\n\n- [Cards](/workspace/add-ons/concepts/cards)\n- [Homepages](/workspace/add-ons/concepts/homepages)\n- [Widgets](/workspace/add-ons/concepts/widgets)\n- [Actions](/workspace/add-ons/concepts/actions)\n- [Event objects](/workspace/add-ons/concepts/event-objects)\n- [Constructing cards](/workspace/add-ons/how-tos/building-workspace-addons#constructing_cards)\n- [Building interactive cards](/workspace/add-ons/how-tos/interactions)\n- [Navigating between cards](/workspace/add-ons/how-tos/navigation)\n- [Using universal actions](/workspace/add-ons/how-tos/universal-actions)\n- [Adding autocomplete to text inputs](/workspace/add-ons/how-tos/suggestions)\n- [Accessing user locales and timezones](/workspace/add-ons/how-tos/access-user-locale)\n- [Connecting to non-Google services](/workspace/add-ons/how-tos/non-google-services)\n- [Style guide](/workspace/add-ons/guides/workspace-style)\n- [Best Practices](/workspace/add-ons/guides/workspace-best-practices)\n\nReference these pages when creating cards and implementing\nUI behavior. You may also find the following additional samples useful to\nreference when implementing your add-on:\n\n- [Google Workspace add-on \"Cats\" quickstart](/workspace/add-ons/cats-quickstart)\n\n This add-on sample shows a simple Google Workspace add-on UI with multiple pages and\n homepages.\n- [Google Workspace add-on: \"Translate\"](/workspace/add-ons/translate-addon-sample)\n\n This add-on sample shows a Google Workspace add-on that lets users translate text from\n within Docs, Sheets, and Slides.\n- [Google Workspace add-on: \"Teams List\"](/workspace/add-ons/teams-addon-sample)\n\n This add-on sample shows a more complex\n Google Workspace add-on sample, that shows\n user information about Gmail message recipients, Drive file editors, or\n Calendar event attendees. You can only use this add-on inside a domain, since\n it uses the [Directory API](/workspace/admin/directory) to retrieve\n user information."]]
