Change width of Phone field

Please check this form http://form.jotformpro.com/form/52246803629963?

I made adjustment by adding this CSS code using the Form Designer.

#input_13_full{

width: 320px !important;

max-width : 320px;

}

You can also clone the form if you like. Follow this user guide to clone
