## Description
Move the position of `fb4` relative to where it is now by adding a `position` of `relative` and `left` of `10%` to it. Do the same for `fb5` but use `right` instead of `left`. This will cover up the remaining white space in between the buildings.
## Instructions
## Tests
```yml
tests:
- text: test-text
testString: const fb4style = code.match(/\.fb4\s*{[\s\S]+?[^}]}/g)[0]; const fb5style = code.match(/\.fb5\s*{[\s\S]+?[^}]}/g)[0]; assert($(".fb4").css("position") === "relative" && $(".fb5").css("position") === "relative" && /left\s*:\s*10%\s*(;|})/g.test(fb4style) && /right\s*:\s*10%\s*(;|})/g.test(fb5style));
```
