Relative unit

The em-based font-size values for .title and h1 are relative to their parent header's font-size value. This causes a compounding issue that makes their font size values larger than the desired values. Replace the em units of .title and h1 with a unit that is relative to the root element of the page.

/* Complete the challenge by writing CSS below */

header {
  font-size: 1.8em;
}

.title {
  font-size: 1.625em;
}

h1 {
  font-size: 5.625em;
}

        As spawning season approaches, the fish acquire a humpback and protuberant jaw. After spawning, they die and their carcasses provide a feast for gatherings of mink, bears, and Bald eagles.

Hi Erica. You want a unit value that calculates sizes based on the root element. So changing your h1 and title to rem rather than em should work.
