Why cant pass this step

Hey @hoangbkcntt98 ,
This challenge has a bug so skip it and move on.
It will not affect your certificates, so do not worry while skipping.
Hope it helps.

i have found a solution for this trouble but its really a bug

One more things, whenever you need help with any of the challenges here on FCC,
Try to use the “ask for help” Button on your challenge page.
It will post your query along with link to the challenge.

If a skip this step, can i have the certificates?

Yes, you definitely can have the certificates.
Here on FCC, it is not compulsory to complete all the challenges, you just have to complete the projects to claim the certificates.
So do not worry.

The tests pass once the order of p and em tags are reversed. @SpaceCatInd found a solution in her post.
