Repeating-linear-gradient with ranges not single color stops

Tell us what’s happening:

It’s asking for a range of stops for each color. I can find no examples with a range for the color stops. I’ve already created repeating-linear-gradient numerous times with single color stops and they worked fine.
I’m only finding examples that have a single stop for each color. Maybe I’m misunderstanding what they’re asking. But now I’m stuck.

“Add a repeating-linear-gradient to .fb1c with a 90deg angle, your --building-color4 from 0% to 10% and transparent from 10% to 15%

Also, I’m not familiar with using “transparent” in a gradient, and can find nothing on that either.
Please help.

Thanks.

Challenge: Step 77

Link to the challenge:

I typed repeating-linear-gradient into Google and found this as the first item in the search result. It shows examples of exactly what to do here.

I can find none with a range for the stops. I’m only finding examples that have a single stop for each color.

--building-color4 from 0% to 10% and transparent from 10% to 15%.

I can find no examples with a range for the color stops.
I’m only finding examples that have a single stop for each color.

Are you able to address that part please?

I see both types of examples. If you only see examples for the single stop color, then try doing that instead. There will be a total of 4 stops. One to start with --building-color4, one for --building-color4 up to 10%, one to start transparent starting at 10%, and final one for ending transparent up to 15%. Give it a try. If you get stuck, post your code for that css selector and we will try to guide you further.

I’m talking about ranges within a single stop though.

I’ve already successfully created repeating-linear-gradients.

They worked fine.

Current ask:
You should give .fb1c a background with a repeating-linear-gradient.

Here’s the current code that won’t pass:
( Can you personally see what’s wrong with it or not?)

.fb1c {
  width: 100%;
  height: 80%;
  background: repeating-linear-gradient(90deg,
    var(--building-color4)  0% 10%,
    transparent 10% 15%);
}

Error Message:

You should use a first color of --building-color4 from 0% to 10%.

Your code accomplishes the task and as far as I am concerned should be accepted. The test behind-the-scenes is very restrictive in what it allows for the “correct” answer. The test is expecting 4 different stops. I think it is not great that the curriculum does not give any examples of the expectations. The new project-based curriculum is a work in progress.

I copied and pasted this code in Visual Studio Code and it works 100%.
And there are 4 stops.

So, I’m at an impasse and cannot proceed.

I have no idea what they think is wrong.

Any idea what should I do?

You have not properly referenced the css variable here. You are missing a -. Even if you fix it, you will still not pass the remaining tests because of the test bug I mentioned above.

It actually has two dashes in the code, not sure why it pasted as one on here. If I attempt to edit on here, the edit text displays two dashes. Weird.

I successfully modified the test to accept your version (more like the docs show) and the version of code which FCC was already accepting. I will submit a PR shortly for the curriculum team to review.
