Could you please help me make the Credit Card information boxes larger and put the Submit button on the form? We are trying to go live ASAP. Thank you!

Hi,

I have cloned your form and this is the fix I have done using css https://www.jotform.com/help/75-Customize-Your-Form-Using-Custom-CSS-Codes

.square-hosted-fields{
height: 25px;
 

}
#input_54{
      margin-top: -25px;
    margin-left: 25px;
}

Hope this helps.
