I have few `div`s like this:

```html
  <div id=1>
    <div id=2></div>
    <div id=3></div>
    <div id=4>
      <div id=5></div>
    </div>
  </div>
```

What I need is set up divs like this:
div 2 is on top left, div 3 is on top right, div 4 is at the bottom right and div5 at the top center of div 4

Problem is that I need to do it only in CSS and without class.
