# --description--
Remove the `background-color` property and value from `bb4` and add it to the three new sections; `bb4a`, `bb4b`, and `bb4c`, so only the sections are filled.
# --hints--
test-text
```js
const bb4 = code.match(/\.bb4\s*{[\s\S]+?[^}]}/g)[0];
assert(
!/background-color/g.test(bb4) &&
$('.bb4a').css('background-color') === 'rgb(83, 140, 198)' &&
$('.bb4b').css('background-color') === 'rgb(83, 140, 198)' &&
$('.bb4c').css('background-color') === 'rgb(83, 140, 198)'
);
