Is there a bug with editor ?

It's impossible to validate task 2 of 3.

If I enter the value during the first step, it was correct in prefview, but on task 2 preview and "check work" didn't update.

Your code is correct, but with CSS, it is not a good idea to round values. You are setting the value correctly, but 53 / 16 = 3.3125 (4 decimal places). Once you fix that, you're good to go.

h2 {
  font-size: 3.3125em;
}

Sometimes when converting to em, you can get very long decimal places... remember to keep all of it.

Hey Emmanuel,

I don't believe there is a bug. You'll need to post the code you are entering for us to help you.

I just went through all three tasks in the challenge with no issues.

Hi,

thanks for your quick reply ! :)

Here is my css code for the second step 

/* Complete the challenge by writing CSS below */

header {
  font-size: 1.8em;
}

.title {
  font-size: 1.625rem;
}

h1 {
  font-size: 5.625rem;
}

h2 {
  font-size: 3.313em;
}

Each time i have the error : Bummer! Is the font-size of h2 an em value equivalent to 53px?

I' don't understand what i am doing wrong.
