Abstract: A system that generates content pages for various devices, browsers, and browser screen sizes is disclosed. A content page generator could use pre-defined templates to populate a content page with blocks of media, such as text, images, video clips, and audio clips. The system will then automatically determine breakpoints which define thresholds where the organization of the content page changes. Client code is generated for the device which will alter the organizational structure of how the blocks of media are presented to a client user depending upon device attributes, such as the dimensions of the screen or the orientation towards a user.
