    How do I increase the field width of the input mask phone field?

    Asked by bminich on February 06, 2015 at 12:33 PM

    I am trying to increase the width of our "Mobile Number" and "Home Number" filed in our Application for Enrollment form. I've tried to go into the Designer but by trying to increase the width of only those two fields, it ends up increasing all the fields in the form.

    You can inject the following CSS via the Form Designer to increase the width.

    .mask-phone-number {
    width: 160px;
    }

    The 160 pixels value can be changed. Please see the following animation.

    If you need any further assistance on this, please let us know. Thank you.
