ATW-CSS-CLASS
The value of ATW-CSS-CLASS should represent a corresponding class in the current theme (that is, a .class-name entry in the cascading style sheet) deployed when you run your program through AcuToWeb. This property can be applied to more than one control in your program.
ATW-CSS-ID
The value of ATW-CSS-ID should represent a corresponding ID in the current theme (that is, a #class-name entry in the cascading style sheet) deployed when you run your program through AcuToWeb. The value of this property must be unique, and only applied to one control in your program.
If both the ATW-CSS-CLASS and ATW-CSS-ID properties are specified for this control, and both correspond to the same style in the style sheet, the style specified by ATW-CSS-ID takes precedence.
