Contact form font size

Site URL: https://gregorylassale.com/

I am trying to customize the contact form fields font (i.e. what users type in). The CSS code below does allow me to change to font type, but the font size value has no effect. Any idea? 

.form-wrapper .field-list .field .field-element
{
font-family:'avenir next';
font-size: 19px; 

Thank you.

Hi Greg,

Please try:

.form-wrapper .field-element {
  font-family: avenir next!important;
  font-size: 15pt!important
}

Worked great. Thank you @ErikaT!
