    [data-type="control_phone"] .form-sub-label-container:first-child {

        width: 100%;

        margin-right: 0;

    I believe you are referring to this form (https://www.jotform.us/form/62919145484161). I opened your form and I was able to replicate the issue.

    Please insert this custom CSS code:

    @media only screen and (max-width: 40em) {
    [data-type=control_phone] .form-sub-label-container:first-child {
    width: 100% !important;

    .form-textbox, .form-textarea {
    max-width: none !important;

    Here's a guide on How-to-Inject-Custom-CSS-Codes. Here's the result:

    Hope that helps. Thank you.
