Methods and systems are described herein for coordinating a plurality of sections of a webpage. A browser application at a client computing device renders a webpage comprising a plurality of sections, each section containing source code. The browser application determines a master section of the plurality of sections using communications between at least a subset of the plurality of sections. The master section determines one or more attributes associated with at least a subset of the plurality of sections. The master section transmits the one or more attributes to a remote computing device, synchronizes a behavior of at least a subset of the plurality of sections, or both.
