你可以用 `hr` 標籤來創建一條寬度撐滿父元素的水平線。 這種水平分割線一般用來表示內容主題的改變，或在視覺上將文檔分隔成幾個部分。
|
||
|
|
|
||
|
|
# --instructions--

|
|
||
|
|
在卡片標題元素 `h4` 下方添加一個 `hr` 標籤。
|
||
|
|
|
||
|
|
**注意：**HTML 中的 `hr` 是自閉合標籤，所以我們不需要爲它添加結束標籤。
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
應存在一個 `hr` 標籤。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert($('hr').length == 1);
|
||
|
|
```
|
||
|
|
|
||
|
|
`hr` 應在標題和段落之間。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(code.match(/<\/h4>\s*?<hr(>|\s*?\/>)\s*?<p>/gi));
|
||
|
|
```
|
