Because of the way Flash control styles are implemented, some common styles are valid, but have no effect, in some tags. Therefore, in the table in Styles valid for all controls in ColdFusion MX Flash Form Style Reference in CFML Reference, the listed styles do not cause errors when used in controls, but might not have any effect.
Styles can be inheritable or noninheritable. If a style is noninheritable, it only affects the tag, and does not affect any of its children. For example, to maintain a consistent background color in an hbox form group and its children tags, you must specify the color in all tags. If a style is inheritable, it applies to the tag and its children.
