Don't merge this. It's just for notes

You can close it whenever, but this is the only way I can comment directly in the code
just like above, i would scrap this selector and use the `&` syntax. i would also stay away from the `>` and give the `ul` a class

```
.nav-item {
  font-size: 1.3em;
  ...

  &:hover .child-list {
    border-radius: 20px;
    display: block;
  }
}
```
