# --description--
Your rows need some background color to help differentiate the data.
The `:nth-child()` selector allows you to target elements based on their position in a group of sibling elements. Create a `.row:nth-child(odd)` selector to target all `.row` elements that are an odd child (child 1, child 3, etc). Give this selector a `background-color` property set to `#dfdfe2`.
# --hints--
You should have a new `.row:nth-child(odd)` selector.
```js
assert(new __helpers.CSSHelp(document).getStyle('.row:nth-child(2n+1)'));
```
Your `.row:nth-child(odd)` selector should have a `background-color` property set to `#dfdfe2`.
```js
assert(new __helpers.CSSHelp(document).getStyle('.row:nth-child(2n+1)')?.backgroundColor === 'rgb(223, 223, 226)');
```
