How to clear Add Flex Superpowers to the Tweet Embed challenge?

Tell us what’s happening:
I don’t know what’s wrong with the code but even though I have added ‘display:flex;’ to header .follow-btn, the test keeps showing this test result ’ Your .follow-btn should have a display property set to flex’. I don’t know how to clear this challenge.

Your code so far

Hello, proprammer.

I have copy/pasted your code into my browser, and it passes the tests. Therefore, I would assume the issue has to do with your browser.

  1. Are you at 100% zoom (I doubt this would affect this challenge, but maybe)?
  2. Do you have a browser extension that has access to change content on fCC?

I hope this helps.
