It did that. meaning that FCC will still be able to access it after i shutdown without saving?
I never been tried that. before shut down, you can copy url and submit your answer.
and remember this. you should save your work before closing code-pen.
Your code is saved on codepen server when you save the changes. You’re providing the link for the same to FCC. Your page can be accessed with the same link by anyone, juts like any other webpage even if you close the codepen from your browser.
