39. The system of claim 34 wherein the one or more preference elements specify one or more user preferences.
34. A system, comprising: a computer memory; at least one hardware processor interoperably coupled with the computer memory configured with: particular code that corresponds to a first module selectively designated for inclusion in a personalized container document, wherein the particular code provides parameters associated with the first module for use in generating module data for the first module, wherein the module data for the first module is adapted for use in the personalized container document, the parameters of the particular code including a first content element and one or more preference elements; additional code that specifies a second module selectively designated for inclusion in the personalized container document, wherein the additional code provides parameters associated with the second module for use in generating module data for the second module, wherein the module data for the second module is adapted for use in the personalized container document, the parameters of the additional code including a second content element; wherein the personalized container document defines an organization for a presentation of content associated with the first module and the second module in a container document display, wherein for each module a portion of the container document display is allocated for the presentation of content corresponding to the module; wherein module data for each module designated for inclusion in the container document is adapted to be served with the container document to a remote browser client, the module data for each module including computer-executable instructions executed on a hardware processor by a remote browser client to render content for the module for presentation in the container document display; and wherein the first content element is different than the second content element and the one or more preference elements include at least one module preference element adapted to specify at least two alternative presentation states of content for the first module, the at least one module preference element defining conditions that change independent of user input in the container document display for dynamically presenting content in one of the at least two presentation states, with content rendered, using the computer-executable instructions executed by the remote browser client, in a first of the at least two presentation states in response to a first condition and rendered, using the computer-executable instructions executed by the remote browser client, in a second of the at least two presentation states in response to a second condition.
