# --description--
Your last `.row` element in each section should stand out, as this is your "total" row. The `:last-child` selector allows you to target the matching element that is the final child in a group of siblings.
Create a `.row:last-child` selector and give it a `background-color` property set to `transparent`. Also set the `margin-bottom` property to `30px` to create some extra space between your sections.
# --hints--
You should have a new `.row:last-child` selector.
```js
assert(new __helpers.CSSHelp(document).getStyle('.row:last-child'));
```
Your `.row:last-child` selector should have a `background-color` property set to `transparent`.
```js
assert(new __helpers.CSSHelp(document).getStyle('.row:last-child')?.backgroundColor === 'transparent');
```
Your `.row:last-child` selector should have a `margin-bottom` property set to `30px`.
```js
assert(new __helpers.CSSHelp(document).getStyle('.row:last-child')?.marginBottom === '30px');
```
