Validation controls whether the respondent's input into a question or action is valid or not. If the result of the expression is "true" (i.e. 1), the "good" class will be applied to the element and validation message. Otherwise, if the result of the expression is "false" (i.e. 0)), the "error" class will be apllied to the element and validation message. You can declare a style for these classes in the template.css.
