I want to build a plugin page with form options and a live preview to auto refresh and display the changes on the frontend. Is it possible to show a live preview of the frontend in the plugin options page?

Similar to WP > Appearance > Customizer but in a plugin options page with custom styled form elements and responsive preview.

What is the best approach you have had success with? Did you use a WP customizer API I do not want to use any framework as this is a very simple project.

Thanks in advance Vinay
