How to force an iframe to load from http on a site that works on https?

Question

Browsers

In general, there is a site (WordPress), everything is set up on it and everything works very well. But after https has been configured, frames (which carry the main semantic load of the site) using http are not loaded. How to make them load and what would it not be considered mixed content?

Answer 1

Do you understand that you are proposing to load a resource (which is mb and js) on a "secured" https page via http, which can be easily replaced by your neighbor, for example?
