# --description-- <del> To use a variable, put the variable name in parentheses with `var` in front of them like this: `var(--variable-name)`. Add your variable as the value of the `background-color` property of the `.bb1a` class. Whatever value you gave the variable will be applied to whatever property you use it on. In this case, your variable has the value of `#999`. So `#999` will be used as the value for the `background-color` property. </del> <ins> To use a variable, put the variable name in parentheses with `var` in front of them like this: `var(--variable-name)`. Whatever value you gave the variable will be applied to whatever property you use it on. Add the variable `--building-color-1` you created in the previous step as the value of the `background-color` property of the `.bb1a` class. </ins> # --hints--

Discussion:
In step 15 of the curriculum called Learn CSS Variables By Building a City Skyline, the instructions fail to provide the name of the variable that is being referenced. The instructions say: Notice that at no point does this paragraph give the exact name of the variable that is to be used to pass this step. ("Add your variable" all of these are not variable names) Instead the instructions should mention the variable name once: To use a variable, put the variable name in parentheses with var in front of them like this: var(--variable-name). Add your variable as the value of the background-color property of the .bb1a class. Whatever value you gave the variable will be applied to whatever property you use it on. In this case, the variable has the value of . So will be used as the value for the background-color property. No response Device: Laptop OS: Windows 11 Browser: Chrome Version: n/a No response
The user is expected to use the variable they created on the last step: That is the only CSS variable that exists at this point in the project. That said, people take breaks between steps, so it can be mildly unreasonable to expect users to remember details from previous steps. Perhaps:
yes please. Also I spent a long time trying to help someone because I didn't realize right away that the variable was being referenced from a previous step. (I could see the hints, but I couldn't understand why the hints were hinting at something I had never seen) (alternate solution that I think would work also is to call out the previous step: "Add the variable you created in the previous step...")
Why not the best of both worlds?
Change the text to: Seems straightforward of a PR. I'll open it for first timers.
Thanks for the update. I had a question about updates and how they make it back to what we see as users in the curriculum. Is there a schedule at all for a release or whenever someone's PR is accepted, it immediately is available to everyone who uses fCC?
Releases aren't done on a specific schedule. We merge into to trigger a staging release (on ), and merge into to trigger a production release.
if no one is working on this issue yet, could i work on this?
Can I work on it if no one works on it?
Anyone can work on an issue - they are not assigned.

We merge the first complete PR to address the issue. The desired new text is listed above.
.bb1a { width: 70%; height: 10%; background-color: var(--building-color1); } here i am getting :- The background-color of the .bb1a element should be set. i dont know what to do?????
open a topic on the forum, the repo is not the place to ask for help in solving the steps
