Django website - Online responsive check

[zakar.u...@gmail.com]

Hello everyone, 

I used django framework for developing a web application.

Now, I'd like to adjust the application to every devices' monitor (desktop, tablet, mobile).

I'm used to using http://responsivedesignchecker.com/ to check website responsive. But while I test my django website through this responsive checker, it display nothing.

I already changed allowed_host value to accept any hosts but same problem (nothing displayed).

So, I don't know what should I do.

Everyone can help me?

Thanks
