Default Delivery Context

A baseline set of device capabilities defined by the W3C Mobile Web Best Practices specification, used as a reference point for evaluating mobile web content. The Default Delivery Context specifies minimum characteristics such as a 120-pixel screen width, XHTML Basic 1.1 support, UTF-8 encoding, JPEG and GIF image support, 20KB maximum page weight, 256 colors, CSS Level 1, and no scripting. It provides a common denominator for testing but does not represent the actual capabilities of any specific device, which can lead to inaccurate evaluation results for devices that exceed or fall below these assumptions.
