Add a background property below the background-color property. Set it as a gradient of type linear-gradient that uses --building-color1 as the first color and --window-color1 as the second.
I was asked to add the above in my project which i did. But it 's still requesting that i should add this “You should give the background a linear-gradient starting from `var(–building-color1)”…
how do i add the above on my project? please…
