# --description--

创建这些分隔线的好处是你可以应用特定的类来单独设置它们的样式。 将 `double-indent` 添加到你的最后一个 `.divider` 的 `class`。

# --hints--

你的最后一个 `.divider` 元素应该将 `double-indent` 添加到 `class`。 不要删除现有值。

```js
const last = document.querySelector('.daily-value.small-text')?.lastElementChild;
assert(last?.classList?.contains('double-indent'));
assert(last?.classList?.contains('divider'));
```
