Can someone help me? Is it a bug?

Tell us what’s happening:
I write it manually and checked on the hint section that nothing wrong but it still says wrong. So, I copied the hint but it still won’t work.

It says:
Your.follow-btnshould have adisplayproperty set toflex.

Your code so far

Hi @nicholasnicho671!

Welcome to the forum!

The code you have shared works on my end. Please ensure that you have disabled any extensions that interface with the freeCodeCamp website (such as Dark Mode and Ad Blocker), and set your browser zoom level to 100%. Both of these factors can cause tests to fail erroneously.
