Disclosed is a system that tracks website usage without compromising user privacy. The system aggregates website usage data of multiple users across multiple websites. Website usage data is aggregated in a way that preserves each individual user's privacy. Specifically, information relevant to a particular user may be obtained from the aggregated information without exposing what was actually collected from that user. In some configurations, user-specific website usage data is aggregated using trusted execution environment computing hardware. This ensures that privacy is preserved while user-specific data is transferred to and processed by the system. The trusted execution environment applies differential privacy techniques to ensure that use of the aggregated information does not reveal actual information about a user's website usage history. In this way, privacy is maintained while still enabling many of the scenarios that would otherwise rely on third-party cookies.

Presentation of accessible content is in accordance with a grid established by rules independent of the content. Different rules establish different grids utilizable with the same content, thereby enabling proper formatting across a wide range of devices and displays. The rules provide for fixed size and auto sized column widths and row heights. Additionally, the rules provide for column widths and row heights size based on fractional weighting of the remaining space after the fixed size and auto sized grid members are accounted for. The grid establishes a coordinate system onto which content is 'hung' by aligning an aspect of the content with a coordinate point. Content is hung by reference to its beginning, its end, its center point, or, alternatively, content can be specified to be stretched to fit the width of the column and the height of the row with which it is associated.
