Finally, create a new rule that targets the h3. Using the same parent font-size context, give the h3 a font-size value

header {
  font-size: 1.5em;
}

.heading {

h2 { font-size: 3em;
}
h3 { font-size; 3.6em;

But wouldn't the parent be h2? which now has a font size of 48px

h3 { font-size; 3.6em;
}

There should be a : after font-size rather than a ;.

The parent element of the h3 has a font-size value of 16px, and the challenge wants the h3 element to have a font-size value of 20px. The value in ems should be 20px/16px, which is 5/4 or 1.25.
