how to configure a disabled form application with an html field

Hi.
I’m having problems to show a simple form app with one html field and two text fields.
But I need all fields to be disabled.
I can’t find the way to turn the three fields disabled. If the three field are text fields everything goes ok. But when I configure the third field to be html field, the three fields became editable.
What am I doing wrong?

I tried an other solution: to build a div that hides all the webpage, and works ok in pc chrome. But it doesn’t work in Chromium (in android). And I need this to be run in an android phone.

Can anybody help me?
thank you.

If someone has the same problem: The issue was that my html code began with <BODY contentEditable=true>
Just changing true to false, solved all the problem
Thank you.

you could use CSS to do so. Pointer-events blocks the property to select a field. Use IF to set this property using ‘echo…’ or ‘?> <?php’

PHP

echo '<script>.classname_element {pointer-events: none;}</script>;

or

​​​​​​​JS

?>
   <script>
      .classname_element {​​​​​​​
         pointer-events: none;
      }
   </script>;
<?php
