Adding custom style to components and containers

Components and containers in Flow are rendered using the HTML5 player, and uses standard CSS for styling. Flow uses the ever popular Facebook React framework.

We can also customize the look and feel of components and containers by overriding their default style, using custom styles (either inline in a custom player, or in a separate stylesheet).

We can add custom classes to a component or container type if we have existing styles that we want to implement.
