Hi Sally,

I copied and pasted your code into the challenge and it passed. Maybe restart your browser?


Yep, that worked. When all else fails . . .

Hey it looks like you're doing it right so I imagine that there's some kind of syntax error you're making that we can't see. Try comparing the below with your answer

/* Write your CSS code below */

h1 {
  font-size: 2.5em;

p {
 font-size: 1.5em; 

Thanks, that is what I have. Refreshing the browser made it work.
