--description--

You want the foreground buildings container to sit directly on top of the background buildings element. Give it a width and height of 100%, set the position to absolute, and the top to 0. This will make it the same size as the body and move the start of it to the top left corner.

test-text

const fb = code.match(/\.foreground-buildings\s*{[\s\S]+?[^}]}/g)[0];
assert(
  $('.foreground-buildings').css('position') === 'absolute' &&
    $('.foreground-buildings').css('top') === '0px' &&
    /width\s*:\s*100%\s*(;|})/g.test(fb) &&
    /height\s*:\s*100%\s*(;|})/g.test(fb)
);
