I’m having an issue with step #40 the error is asking me to add a background to the bb1a class element. I have a background property with a linear-gradient function and added the variables. I tried looking up the linear-gradient function, but it’s asking me to add a background to bb1a.

here is my css code so far:

.bb1a {
width: 70%;
height: 10%;
background-color: var(–building-color1);
background: linear-gradient(–building-color1, --window-color1);

From what I see you’ve forgotten to call the variable with the var function within your linear-gradient function.

.bb1a {
width: 70%;
height: 10%;
background-color: var(–building-color1);
<!--  Look below here -->
background: linear-gradient(–building-color1, --window-color1);
<!-- Look above here -->
              
this is a helpful comment because the example syntax that is shown at step 40 is incorrect;
gradient-type(
 color1,
 color2
since this does not work;
background: linear-gradient( 
    var(--building-color1),
    var(--window-color1)
I tried your alternative method;
background: linear-gradient(var(--building-color1, --window-color1));
it did not work either.
This is not.
Can you post the code to your latest attempt of what you think should be correct?
Remember. To call variables, you need to call var() function and put the name of the variable inside the arguments (inside the brackets).
              
Hi @jasperstam
Can you post all of your CSS code using that method?
Enclose it in a triple backtick like this
```css
paste css codes here
That would be much appreciated
              
Hi @jasperstam.
I just posted a hint for this step and for this exact issue not long ago.
