Under "Question Look & Feel" there is an option to change the look of the Label Cell and Field (which is needed against different container looks/colors)

Is there a list of these codes/samples somewhere?  Thanks!

You might check out some of the look and feel demos at http://www.datasprings.com/formdemos. I don't know that there are any directly though... You might try looking up 'Textbox CSS Class' and so forth, basically this can enable you for example to have a blue background etc... For example, if you named the class DynamicForms_MyTextbox you could create a stylesheet class under module configuration such as....

.DynamicForms_MyTextBox {
BackgroundColor: #00FF00;

}
