Need Form Field to hide but show text input

Hello community! 

Thwre is probably an easy solution for this but I'm stumped. So I'm turning to you all. 

I have a client that wants to take a design I created and turn into a template that she can email to every center location. Each location will then fill in the parts to make it tailored to their center. Like entering their website, email address, and phone number. I created it exactly how she wanted with the areas to enter in the information as a form field. So far no problem.

The thing is, she now wants it to not look like it was a fillable form field after they input their text information. She says they might want to email it to their clients and customers after they insert their information and it doesn't look professional if the areas they filled out look like they filled it out.

So my question is how do you get the forms fields to disabled after they input their information while leaving their information still visible?

Appreciate any advice or "input" (hahaha pun) you all might have! 

Thanks!
