Techniques are provided for segmenting digital content into a plurality of tiles which can be displayed across multiple application windows. For example, in one specific implementation, the methods disclosed herein can be used to segment a webpage into a plurality of tiles, wherein each of the tiles can be displayed in a separate web browser that displays a portion of the original webpage. In general, each content browser identifies which tile it displays based on a configuration that can be stored locally by the browser. To maintain interactivity such as may be provided by active content, each browser includes a mutation observer configured to detect changes in a document object model (DOM) and/or cascading style sheet (CSS) associated with the displayed content. Detected changes are recorded in notification messages which can be broadcast to other content browsers via a WebSocket connection or a direct peer-to-peer network.
