CSS - loginbox alignment

Hello everybody!

As you can see in the image below, I have the first entry page with the content aligned to the left.

The problem is that I can’t find a way to align the 16 digit code input form (which I think is the id=“WhistleblowerLoginForm”) in the same way - left.

I’ve tried several CSS options but the result is always centered!

Can anyone give me a hint on how to solve this?

Thank you so much!
