CSS CSS Basics (2014) Understanding Values and Units Em and Rem Units

Issues with an answer

Had this question: Create a new rule that targets the h3. Using the same parent font-size context, give the h3 a font-size value in ems equivalent to 20px.

gave this answer: h3 { font-size: 1.250em; }

What am I doing wrong?

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

header {
  font-size: 1.8rem;
}

.title {
  font-size: 1.625rem;
}

h1 {
  font-size: 5.625rem;
}
h2 {
font-size: 3.3125em;

}
h3 {
font-size: 1.250em;

        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:

Ok, after running through the problem I found that the issue is with the zero at the end of your 1.25em. So instead of 1.250em it should be 1.25em. Hope this helps :)

Try changing it to

h3 {
    font-size: 1.25em;
}

I don't think it likes a trailing zero!
