This, what the lesson shows you, is a sample of how you would style the id;

#cat-photo-element {
  background-color: green;
}

What you need to do is style the id in the form so that it’s similar to that. What is the id of the form in the lesson?

ok got that far need the rest

id= "cat-photo-form"
in the <Form action="/submit-cat-photo" id="cat-photo-form">

I can’t see what you typed. If you typed in code the first line needs to be three back ticks, second line, etc your code and the final line three back ticks.
