BaseUI is a layout manager written in actionscript 3 that will help you to handle the positions and sizes of DisplayObject (MovieClip, Sprite, Video, Images and so on). BaseUI makes things easy when you want to manage backgrounds and assets behaviors in a liquid or fixed flash site.
You will be able to use new properties on your DisplayObject, such as top, bottom, left, right, horizontalCenter, width and height (also with percentage values), ratio mode for backgrounds, etc.
BaseUI also contains layouts you can find in the Flex Framework: CanvasUI, TileUI, HBox, VBoxUI.
