    Change the font size of a sublabel

    Asked by sisters7 on March 12, 2017 at 09:15 AM


    I want to add "Need a power Scooter? Please contact..." as a sublabel under Physical Limitations. I want the font a little bigger than the default size. Please let me know what to do. Thanks.

    I checked your form and I can see that you haven't added the sub-label yet. In Form Builder V4, you can click the "Type a sublabel" under the text box and enter the sub-label.

    You can increase the font size through custom CSS. If you are targeting only this sub-label, use this CSS code:

    #cid_10 .form-sub-label {
    font-size: 13px;

    If you want to change all sub-labels, use this code:

    .form-sub-label {
    font-size: 13px;

    Here's a guide on How-to-Inject-Custom-CSS-Codes. Hope that helps. Thank you.
