I have a project where I need to make a page builder in the backend of WordPress(sort of like the WP native customizer). Issue I am having is that I cant load the theme CSS styles for this builder to have a preview without breaking the WordPress backend styles. I was thinking of using an iframe just like how WordPress does it but I would have to create a HTML file to load into the iframe I am guessing? If so that’s not an option because WordPress VIP doesnt allow creating files(or file access). So is there any other way I can go about doing this? I am kind of new to the WordPress dev side of things so I need some help on what my options are. Thank you so much for the help!
