style.css
/* Write your CSS code below */
h1{
  font-size:2.5em;
}
p{
  font-size:1.5em;
}
.more{
  font-size:1.2rem;
}

What about:

.more {
  font-size: 1rem;

}

Does that work?

Hi again Juliana,

A rem is a 'root em' and the default value is 16px. Based on the usual calculation of font-size divided by (in this case) 16 the value would be 1rem.

.more {font-size: 1rem;}

Hope that helps again :)
