 ## Goals
 CSSLayout is a cross-platform implementation of flexbox. The goal of CSSLayout is allow native developers to have the same expressive layout system as developers developing for the modern web are used to. CSSLayout allows developers for web, android, iOS, and windows to use the same layout primitives across platforms. This saves time, increases collaboration between platform teams, and makes it easier for developers to work on multiple platforms.
