Basic CSS: Specify How Fonts Should Degrade

this is my code and on stuck “your h2 element should use the font Lobster”
well on h2 in font-family i got Lobster. i don’t why it saying your h2 element should use the Lobster

.red-text { color: red; } h2 { font-family:Lobster, monospace; }

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

Read the rest of the instructions. The point of this is to make the font fallback to monospace in the absence of Lobster.
