NET 2.0 and later, the StyleCollection class can be used by server control developers
to store and manage Style objects for a control. Style objects stored in a StyleCollection
object are applied to different portions of the control.
The best example of how a StyleCollection object can benefit control developers is a hierarchical
control, such as the ASP.NET 2.0 and later Menu control. The Menu control allows an
ASP.NET developer to define a Style by menu depth in the control. The StyleCollectionDemo
web form provides an example of how this works by declaratively providing three Style objects
in a LevelMenuItemStyles tag:

ForeColor="Green" Font-Underline="False" />
ForeColor="Orange" Font-Underline="False" />
ForeColor="Red" Font-Underline="False" />

The MenuItemStyle objects declared in the preceding tag are applied in order of level,
so the first MenuItemStyle with a BackColor equal to "Beige" is applied to the top-level menu.
The second MenuItemStyle applies to the next submenu level, and so on.
