Hi Nick,

Actually 20px should be divided by 16px, not 53px. Remember second question says regarding font-size value of 16px.

"The h2's parent element has a font-size value of 16px. Use an em unit to give the h2 a font-size value equivalent to 53px."

Finally, 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.

h3 {
  font-size: 1.25em; /*20px / 16px*/
}
