What does this error mean?

I’m on Import Google Font Challenge.
I’m unable to meet the following test :

You should use an h2 CSS selector to change the font.

What does this mean. My code is here

<link href="https://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" type="text/css">
  .red-text {
    color: red;

  p {
    font-size: 16px;
    font-family: monospace;

    font-family : Lobster;
    color: red;

<h2 >CatPhotoApp</h2>

This is the same issue, check it out:

your h2 should have a css font. the code you inserted is correct but after font-family you made a space the space is not allowed. like this

font-family:  Lobster; 

No it is not. My google font import is outside the tag.

thank you Aben. That totally worked !
