Form Field Text Input Sizes Vary - How to Make Consistent?

The input text sizes vary across the different forms fields. I used this CSS code previously, but it no longer seems to work:

.form-wrapper .field-list {
 .field {
   .caption {
     .field-element {
       /* Text in the field boxes (First Name, Last Name) */
       font-size: 1.2rem;
     }
   }
   .field-element {
     /* Text in the field boxes (inc placeholder text) */
     font-size: 1.2rem;
   }
 }  
}

Any assistance is greatly appreciated. I'd like all the input text across all fields to be the same size.

Thank you in advance,

Stephen

Can you share link to page where you use form? We can check code easier

Certainly - See below:

I entered the site URL in the topic form (empty form attached for reference) with the original post, but this forum seems to have an issue of not showing it anywhere after it's posted... That needs to be fixed too 😛

This works - Thank you!
