hello again!
I have in my survey a question with "multiple short free text" subquestions and validation(is_empty) in 3 of the subquestions to prevent the field is empty.
is any way to change the label color of the field when the validation of "is_empty" occurs? when the "next" button is pressed. Like when you set the question as a mandatory question.

Yes, you can do that by adding some CSS.
This may come in handy: www.limesurvey.org/manual/The_template_e...g_questions_with_CSS
You can change the color on general basis or by using the sqga notation, you can set it only for a specific question / subquestion.

Thaks!
I try with CSS
