Real site CSS/HTML inject not working on Phishlet

What do I do?
The real site injects a “password” input inside the form once “username” is entered. When i input a username on my site ie; xxx.fake.com a loading spinner appears just like the real site but then nothing happens - (“password” input does not appear under the “username” input on the login form). I also had an issue where the whole page was missing styles but i fixed that through logic i’ve learned with fluxx. It’s probably not working because i had to implement this logic. Any advice is welcomed.

which methods u have tried ?
injecting from subfiler , from inject js,from dynamic injection or someting else ?

injecting from sub, also from js injecting, it’s not working properly. i think this is something you would need to take a closer look at tbh, it will be hard to understand without seeing for yourself.
