I'm having an issues with learn html and css

[greenebeccah]

I’m having some trouble in the style.css portion of the exercise. I’m stuck on adding a selector for fontsize. I put the following:
p {

}
h1 {
color:Firebrick;
}
font-size:18px;

On the left hand side it’s showing that I don’t have the correct selector for the font size. Will someone help?

You have put font-size out of everything.

p{
//is empty
}
h1 {
  color: Firebrick;
}
font-size:18px; 
/* this font size is not declared to anyone */
