An authoring tool for authoring wrap packages of cards. The authoring tool includes a set of tools that enable an author to create a new card of a wrap selected from a variety of card templates. In various embodiments, the card templates include textual, video, image/photo, document, gallery, chat, widgets, global components, location/GPS, transact, appointment, and end-of-wrap card templates. When a particular card template is selected, the template is then duplicated to create the new card. Thereafter, the author may author the card to include various components, content, attributes, layouts, styles triggers and/or behaviors. As the cards of the wrap are created, the authoring tool provides the author with the ability to order the sequence of the cards. The authoring tool thus enables authors to selectively create wrap packages that include media that conveys a narrative story and application functionality.
