These examples are type 3 RESTful API requests and responses. The JSON-HAL specification is used to implement HATEOAS.
Some of the examples are based on my work as architect of the RESTful API at http://www.hautelook.com. All proprietary information has been removed.

The reflow appens as many times as there are frames per seconds. It recalculate all positions that change in order to diplay them. Basically, when you scroll you execute a function where you move things between two reflows. But there are functions that triggers reflows such as jQuery offset, scroll... So there are two things to take care about when you dynamically change objects in javascript to avoid too many reflows:
