Hi.
In this challange main thing is “inherit styles”.
Inheritance means in this case - body is parent of h1 and h1 can take styles like color, background, font-size, font-family. Check more info here
Other words if you define
body {
color: red;
} then
h1 will take color: red; automatically.
But if you define
h1{
background-color:green;
} then body will not accept style rule background-color: green;.It will be defaul #fff
So lets take a look at your code. We need make h1 color: green but not define inline style like h1 color=“green” .
So we can define
body{
font-family: Monospace;
color: green;} for body. Then h1 will take style font-family:Monospace;. and color: green;
