Description
You can specify where you want a gradient transition to complete by adding it to the color like this:
gradient-type(
  color1,
  color2 20%,
  color3
);
Here, it will transition from color1 to color2 between 0% and 20% of the element and then transition to color3 for the rest. Add 80% to the --building-color1 color of the bb1d gradient so you can see it in action.
Instructions
Tests
tests:
  - text: test-text
    testString: const bb1d = code.match(/\.bb1d\s*{[\s\S]+?[^}]}/g)[0]; assert(/background\s*:\s*linear-gradient\(\s*orange\s*,\s*var\(\s*--building-color1\s*\)\s*80%\s*,\s*var\(\s*--window-color1\s*\)\s*\)\s*(;|})/g.test(bb1d));
