ERROR while learning HTML


Hello guys, I'm very new to Codecademy and I'm learning html. I have this problem, see the picture. I cant submit code because it says I've entered wrong px's on third line

(16 instead of 10 px's) , but I didn't..don't know what to do.


When troubleshooting, start looking for typing mistakes. In this case you should wonder "The 10px is correct so why isn't my font-size being recognized, what else could be wrong?" That will help you spot the problem.
