Hey Calista, welcome to the forum.

Please tell us, what issue you are having in Tell us what’s happening: section.

My header tag under the class of main section is marked wrong…and I don’t know what’s wrong

I think you may have found a bug, if I am not misunderstanding something.

<a href="#CSS_Properties">CSS<a/>

In #CSS_Properties section, the a anchor position is misread, which lead to your code not passing.

Deleting it made the test pass, but you need to account for adding it somewhere else for you to pass the project.

Edit: you don’t have to account for adding it, I deleted <code> while testing.
Deleting the said line will make your code pass

Thank you …it worked!
