Repeating-linear-gradient test fail

Test is failing
this is a part of code that fails to pass the test:

.bb2b {
  width: 100%;
  height: 100%;
  background: repeating-linear-gradient(var(--building-color2) 0%, var(--building-color2) 6%, var(--window-color2) 6%, var(--window-color2) 9%);
}

So even though the test fails, the preview part displays exactly what has been described in the task.
This is the message given to me after failing:

Test

Sorry, your code does not pass. Don't give up.

## Hint

You should change the `background` property of `.bb2b` from using `linear-gradient` to using `repeating-linear-gradient` .

Never mind,

had a big mess with passing my solo project so after creating a post about it in forum I have moved on to next course and somehow after submitting my project next part of the course (Building a city skyline) lost it’s progress, this task came up with empty text.
So I copied what passed the previous task and it had me stuck here, until I ended up restarting the task and it finally gave me a fragment of code to edit which then passed…

Sorry for the fuss.
