Translation enhancement for Target a Specific Child of an Element Using jQuery

## Challenge Link
- [Target a Specific Child of an Element Using jQuery - Chinese](https://freecodecamp.cn/challenges/target-a-specific-child-of-an-element-using-jquery)
- [Target a Specific Child of an Element Using jQuery - English](https://freecodecamp.com/challenges/target-a-specific-child-of-an-element-using-jquery)

## Enhancement
- Original description:
> jQuery uses CSS Selectors to target elements. target:nth-child(n) css selector allows you to select all the nth elements with the target class or element type.
- Our translation (NOT ACCURATE):
> `target:`

> 选择目标元素的所有**子元素**

## Suggestion
- Should be `.target`
- 选择目标元素的所有**元素**
