Style consolidation and optimization with strong ownership

摘要

Techniques are described for optimizing and consolidating style files for formatted pages of data such as web pages. Styles may be consolidated through the identification of common rules shared by multiple styles, and the common rules may be incorporated into a common style that has the style mappings and/or namespace of the source styles. Consolidation may enable minimal style information to be sent in response to a page request, the style information corresponding to a requesting browser type and/or version. Embodiments may also provide for global constants in style rules, with global constant resolution performed dynamically at runtime. Embodiments may also support file splitting for optimal browser performance, with the style file splitting performed dynamically at runtime.
