Challenge Task 1 of 3 (Em and Rem Units) Replace the em units of .title and h1 with a unit that is relative to the root

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.

How do I replace the em units of .title and h1 with a unit that is relative to the root element of the page.

style.css 
/* Complete the challenge by writing CSS below */

header {
  font-size: 1.8em;
}

.title {
  font-size: 1.625em;
}

h1 {
  font-size: 5.625em;
}

        Lake Tahoe is one of the most breathtaking attractions located in California. It's home to a number of ski resorts, summer outdoor recreation, and tourist attractions. Snow and skiing are a significant part of the area's reputation.

        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.

        Lake Tahoe is full of wonderful places to stay. You have the ability to sleep in the outdoors in a tent, or relax like a king at a five star resort. Here are our top three resorts:

Replace em with rem. For example, 1.625rem.

I have a feeling that this solution is incorrect and there is a mistake. Parent <heading> is 1.8em, so we should calculate other values for <span> and <h1> relative to the 1.8em. Please, check that, Although system says that your solution is correct.
