Using global, custom, and class styles in the same document

If you define a style in only one place in a document, Flash uses that definition when it needs to know a property's value. However, one Flash document can have a variety of style settings--style properties set directly on component instances, custom style declarations, default class style declarations, inheriting styles, and a global style declaration. In such a situation, Flash determines the value of a property by looking for its definition in all these places in a specific order.

Flash looks for styles in the following order until a value is found:

1. Flash looks for a style property on the component instance.
2. Flash looks at the styleName property of the instance to see if a custom style declaration is assigned to it.
3. Flash looks for the property on a default class style declaration.
4. If the style is one of the inheriting styles, Flash looks through the parent hierarchy for an inherited value.
5. Flash looks for the style in the global style declaration.
6. If the property is still not defined, the property has the value undefined.
