Just relooked the challenge. The second task wants you to use an em unit. Try this. Hope it helps. The em for 48px is this case is 3em.

h2 {
      font-size: 3em;
}

Hey guys,

Each snippet here is what the challenge is looking for for these 3 tasks.

/*For the first task it wants you to change the '.heading' to a relative unit (rem).*/

.heading {
  font-size: 5rem;
}

/*The second task is asking you to target the 'h2' element and give it a 'font-size' equal to 48px in 'em'. With 16px being the base size, 48px is equal to '3em'. 48/16=3*/

h2 {
font-size: 3em;
}

/* The third task wants you to assign an em value equal to 20px for the 'h3' element. Again, using 16px as the base size, this equals 1.25 em. 20/16=1.25*/

h3 {
font-size: 1.25em;
}

I hope this works for you both!

I'm having the same exact issue. I've tried all of the suggestions above. The preview screen also gets stuck on loading. I'm using Chrome, not sure if that's relevant.
