How to make mixed http/https content work?

Question

Google Chrome

An error occurs when opening the page

this request has been blocked the content must be served over https

The bottom line is that the main server where the project code was transferred to https and the server where the pictures, JS, etc. not yet, and the browser does not just issue some kind of warning, but does not load CSS at all (although it displays pictures).
Is it possible to allow loading resources via http somewhere in the browser settings? waiting for the admins to transfer these servers to https may take a long time. But it is impossible to work without CSS, JS.

Answer 1

Remove links to http statics, leave

//foo.bar/main.css
//foo.bar/static/main.png

Answer 2

If these CSS and JS are some popular libraries, then use a CDN. For example, from CloudFlare . And store the styles and scripts of your project on your own server.
