    Adjust Form Fields

    Asked by treybrad on June 06, 2015 at 05:13 PM

    Is there a way to adjust the length of the form fields on this Authorize.net form.


    Note: Amt field, along with Expiration Month and Year are longer than I'd like and I'd prefer they be on the same line.

    In order to adjust the lenght of the fields Expiration Month and Year please inject the CSS Code that follows:

    .form-dropdown.cc_exp_month {
        max-width : 75px;

    .form-dropdown.cc_exp_year {
        max-width : 100px;

    You may include the CSS Code as follows:

    1 - Click on Preferences, from the Preferences screen, click Form Styles, then Inject CSS Code:

    I am sorry but what is the Amt field?

    I hope this helps.
