Learn CSS Variables by Building a City Skyline - Step 78

Tell us what’s happening:

Below is the Problem Statement

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.

Since I have added --building-color4 from 0% to 10% but it is not working. I am not getting what mistake I am making?

Your code so far

<!-- file: index.html -->

/* file: styles.css */
/* User Editable Region */

.fb1c {
  background: 
    repeating-linear-gradient(
      90deg,
      var(--building-color4) 0%,
      var(--building-color4) 10%,
      transparent 10%,
      transparent 15%
    ),
    repeating-linear-gradient(
      90deg,
      var(--building-color4) 0%,
      var(--building-color4) 10%,
      var(--window-color4) 10%,
      var(--window-color4) 90%
    );
}

The second repeating-linear-gradient doesn’t have 90deg direction.
