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

can not move past this one step :(

Challenge Task 1 of 3

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. Replace the em units of .title and h1 with a unit that is relative to the root element of the page. Bummer! Make sure you're setting the font-size of .title using a rem unit.

/* Complete the challenge by writing CSS below */

header {
  font-size: 1.8em;

.title {
  font-size: 1.65rem; /* 26px/16 */

h1 {
  font-size: 5.625em;

You have everything right so far except a couple small issues.

1: It says to change the h1 and the .title font-size values to eliminate the compounding issue error. To do this you would simply change the 'em' value after 5.625 AND 1.625 to 'rem'

2: This is how your code should look for .title:

   .title {
      font-size: 1.625rem;

You have everything right in this code except instead of 1.65em it is supposed to be '1.625rem'. The reason for this is because 16px is your standard em size and you want the font-size for .title to be 26px. When you divide 26px by 16px the answer is equal to 1.625. Hope this helps!

oh ok, i get it now! I only changed the title em to rem instead of all the em's to rems...haha ops, thank you!!

header { font-size: 1.8em; }

.title { font-size: 1.625rem; } h1 { font-size: 5.625rem; }

actually all you need to do is change the 1.625em to rem as well as the h1 font size from 5.625em to rem.
