Learn CSS Variables by Building a City Skyline - Step 78

Tell us what’s happening:

Quest:

You can add multiple gradients to an element by separating them with a comma (,) like this:

gradient1(
  colors
),
gradient2(
  colors
);

Add a repeating-linear-gradient to .fb1c below the one that’s there; use your --building-color4 from 0% to 10% and --window-color4 from 10% and 90%. This will fill in behind the gradient you added last.

but, at the end, it shows a warn message, and i don’t understand:

You should not alter the first repeating-linear-gradient .

Your code so far

.fb1c {
  width: 100%;
  height: 80%;
  background: 
    repeating-linear-gradient(
      90deg,
      var(--building-color4) 0%, 
      var(--building-color4) 10%
    ),
    repeating-linear-gradient(
      90deg,
      var(--window-color4) 10%, 
      var(--window-color4) 90%
    );
}
