Hi Güven Memis, you forget to type 1 before the 2. 53/16 = 3.3125 not 3.325. I think this cause the error in the quiz.

}

.title {
  font-size: 1.625rem;
}

h1 {
  font-size: 5.625rem;
}

h2 {
  font-size: 3.3125em;
}

Then I think you success this code challenge :)

Have a nice weekend! Christian
