Problem to style form fields with error

[Guido Luis Dalla Vecchia]

Hello! I'm building my first website with Django and I've been stuck for the past two months with a problem I can't figure out.

My website has a form with three fields that allow the user to input his first name, last name and email.

In my "forms.py" file, I've declared "clean" methods for each field, that add the "error" class to them if they don't pass the validation.

In my CSS file, I declared a rule that applies the "background-color: lightcoral" to all elements with the class ".error".

The problem is that, when I fill in the "last name" field with invalid data, the "first name" field gets marked as invalid too.

I've tried everything I could think of, and nothing has worked. It's driving me crazy!! Has anyone ever seen something like this?

Pleas help!!!

Can you share some code snippets?

Here I attach the relevant parts of the files "views.py", "index.html" and "forms.py" so you can check them out.

Thanks!
