Hi Xu,

3.3125em is what you should enter, instead of 3.312em.

You can use the following website as a reference: http://www.w3schools.com/tags/ref_pxtoemconversion.asp (the website given in the teacher's notes of the corresponding video would give you 3.313em)

Happy coding. :)

Because the answer is 3.3125em, the challenge requires the precise value, and you missed the last digit.

Hi Xu Cheng

You're almost correct, your answer just needed to be a little more precise. The correct answer is 3.3125em.

h2 {
  font-size: 3.3125em;
}
