CSS CSS Basics Understanding Values and Units Em and Rem Units

create a new rule that targets the h3. Using the same parent font-size context, give the h3 a font-size value 20px

parent font-size is 16px. 1.8em= 28.8px. Shouldn't h3 be -0.55? (28.8px - 20px = 8.8px / 16px = 0.55) PLEASE HELP.

/* Complete the challenge by writing CSS below */

header {
  font-size: 1.8em;

.title {
  font-size: 1.625rem;

h1 {
  font-size: 5.625rem;

Hey Anthony,

As with the previous task in this challenge, the parent font size is 16 pixels. Just simply divide the targeted h3 value of 20 pixels by 16 pixels to get your resultant em value. 20px/16px = 1.25em.

Thank you Rick!
