Pinning a Callout Animation

摘要

Animation for the attachment of content items to a location on a content surface in a user interface is provided. A user interface showing a content surface may be displayed on a computer. The content surface may include a content item at an initial position above the content surface. The content surface may display content formatted for display over an area comprising a totality of the content surface. The computer may then receive in the user interface a request to attach the content item to a final position on the content surface. The computer may then display an animation of the content item moving, from the initial position, across the content surface until the final position has been reached. The computer may then attach the content item to the content surface at the final position.
