Standard default.css has to be copied

[oaubert]

The standard default.css has to be copied in the app using the timeline component. Find out how to embed the default.css, while allowing to override it.

The default.css name should not be used. Instead, a custom Timeline.css should be defined and included in the component through a <fx:Style source="../assets/Timeline.css"/> (or the actionscript equivalent).
