# --description--

The skyline is coming together. Fill in the `background-color` property of the foreground buildings. Use your `--building-color1` variable to fill in `fb3` and `fb4`, `--building-color2` for `fb5`, `--building-color3` for `fb2` and `fb6`, and `--building-color4` for `fb1`.

  $('.fb1').css('background-color') === 'rgb(83, 140, 198)' &&
    $('.fb2').css('background-color') === 'rgb(204, 102, 153)' &&
    $('.fb3').css('background-color') === 'rgb(170, 128, 255)' &&
    $('.fb4').css('background-color') === 'rgb(170, 128, 255)' &&
    $('.fb5').css('background-color') === 'rgb(102, 204, 153)' &&
