Put the display: flex in the right place

Tell us what’s happening:
it says i am not putting it into the follow.btn place but there is no singular place for that i have tried different combinations but i just can’t get it to pass… also i have passed all of these classes before the system got messed up and am supposed to be working on my tribute page, but i can’t figure out how to get that testing part of it to show up on the codepen pages… could someone explain to me how to do that?

Challenge: Add Flex Superpowers to the Tweet Embed

It seems like this might be a bug in Firefox. Try it in Chrome and see if it works.

I am not sure if you are saying you have tried all of the combinations, but you have not put display: flex in either the header .follow-btn, header .profile-name, nor the header .follow-btn sections. And it is not supposed to be in the header .follow-btn button section. Which you do not have.

I would recommend resetting the code, as it seems you have deleted a section of the CSS.

Hope this helps.

They have display: flex; in all the correct sections, and while having it set in header .follow-btn button is not asked for in the challenge, it doesn’t stop the challenge from passing. If you copy/paste the code into Chrome it passes.

I opened up an issue about this, and it seems like in my case uBlock Origin was causing a conflict and not allowing the challenge to pass in Firefox. If you turn it off, it should allow the challenge to pass.
