Hello I need to hide the red asterisk on the required fild on my card form.

I've already find by browsrer inspection the label numbers of my required fileds and extraxt the following css code to put in my form, but on the card form there is no css tab in the design button.  

#label_11 .form-required, #label_12 .form-required, #label_13 .form-required, #label_14 .form-required, #label_15 .form-required, #label_18 .form-required, #label_17 .form-required, {

  display: none;

}

My website is on wordress.org and I import the form using the related script or by popup elementror plug in.

Can you help me?

Thank you in advance for your kindly support.

Unfortunately the Card Layout doesn't support Custom CSS yet. I have submitted the feature request to our developers and you will be notified as soon as possible. We are sorry for any inconvenience caused.

We are currently investigating why our users needs CSS injection on JotForm Cards. As my colleagues has already mentioned, JotForm Cards has no CSS injection feature but if you can tell us which styles and how you want to change with custom CSS, we will try to find a way to meet your requirement. 

Waiting for your valuable returns.

As we did not hear from your side, we want to send a second notice you regarding your CSS request. We would be pleased if you can tell us why you need this feature, to change which styles and how?
