Hey! it looks like you’re using the wrong syntax for using variables in CSS. it should be var(–building-color1) and so on.

Hope this helps! :smile:

3

I’m writing it out just like you specified and I’m still getting an error message that a background needs to be applied to .bb1a

4

your code seems to run for me when i use this syntax.

var(-–building-color1)
5

Please explain how you did it

6

This is the code I have now and it’s still telling me that I need apply a background when it looks to me like I’ve already done that.
Here’s the code so far for Step 40
width: 70%;
height: 10%;
background: linear-gradient(–-building-color1,–-window-color1);
background-color: var(–building-color1);

7

Your code looks good.
You need to delete the background-color with the value for the code to pass

8

I rewrote everything and deleted the background color and it’s still not passing

9

Thanks for your help I figured it out

10

Great.
Glad to hear that.

11

I’m also having the same problem can you help?

12

If I remember right I just did background: linear-gradient(–-building-color1,–-window-color1); and then removed the background-color property that was below it.

13

I have done it exactly like you said and it still tells me that its wrong. Is there something I could be missing?

14

thank goodness i preserved it somewhere else but I’m pretty sure this is what finally passed
background: linear-gradient (var(–building-color1), var(–window-color1));

15

Thank you very much it passed now
