Use an *id* attribute to style an element

Tell us what’s happening:
Describe your issue in detail here.
Please someone to help me here. I have spent two days going ove this and I believe there is something I don’t understand or the system is wrong… the error messages are 1. Your form element should have the background-color of green; 2. Your form element should have an id attribute. Meanwhile the instructions say You should not give your form any class or style attribute. How so?

Challenge: Use an id Attribute to Style an Element

Link to the challenge:

What I’m noticing is that you have just copied the id from the example. That id is different from the id on your form.

I still don’t understand where to go.
The whole thing is now so confused. What happens if I reset?
