# --description--

Nest four `div` elements in the `bb1` container. Give them the classes `bb1a`, `bb1b`, `bb1c`, and `bb1d` in that order. This building will have four sections.

# --hints--

```js
const bb1 = $('.bb1')[0];
assert(
  bb1.contains($('div.bb1a')[0]) &&
    bb1.contains($('div.bb1b')[0]) &&
    bb1.contains($('div.bb1c')[0]) &&
    bb1.contains($('div.bb1d')[0])
);
