Challenge: Learn HTML Forms by Building a Registration Form - Step 42

Link to the challenge:

You are very close but you have added some characters that shouldn’t be there. Look closely at the example:

p:last-of-type { }

Do you see parentheses in that example? How many colons do you see in that example.

there shouldn’t be any parenthesis in the last of type line. And the colon is used once in the beginning of the fieldset last of type element.
It should go like this:

fieldset:last-of-type{
border-bottom: none;
}
