If I copy-paste your code I pass all the tests.

the screenshot you show, those are not FreeCodeCamp colors…

deactivate the dark reader extension please, you can turn on fcc own dark mode from the menu

thanks for your reply. I have checked many many times, still can’t find the error, also can see from the output, the h2 text is blue color.

Thanks ieahleen for your msg. I do find my dark reader setting make fcc screen ugly and difficult to read. will try your suggestion.

Thanks, ieahleen. I follow your suggestion and use fcc night setting. the screen looks so beautiful now. Also after that, I run the test again without changing any code, this time I pass. Thank you so much all.
