target radio labels that are required for styling

Hi,

I have tried any given combo of these options below. Trying to ensure both required and non-required labels for radio buttons and check boxes do not bold.

Can you suggest something other to try?

.mktoForm .mktoCheckboxList > label, 

.mktoForm .mktoRadioList > label {

   font-weight: normal !important;

}  

  .mktoRadioList label {

    font-weight: normal !important;

  }

  .mktoCheckboxList label {

    font-weight: normal !important;

  }

   .mktoRadioList .mktoRequired label {

    font-weight: normal !important;

  }

  .mktoCheckboxList .mktoRequired label {

    font-weight: normal !important;

  }
