# --description--

|
|
|

|
`hr` タグを使用すると、それを囲む要素の幅を横切る水平線を追加できます。 これは、トピックの変更を表したり、コンテンツをグループごとに視覚的に区切ったりするために使用できます。
|
||
|
|
|
||
|
|
# --instructions--
|
||
|
|
|
||
|
|
カードのタイトルを含んでいる `h4` の下に、`hr` タグを追加してください。
|
||
|
|
|
||
|
|
**注:** HTML では `hr` は自己終了タグであり、終了タグは必要ありません。
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
コード内でマークアップに `hr` タグを 1 つ追加する必要があります。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert($('hr').length == 1);
|
||
|
|
```
|
||
|
|
|
||
|
|
`hr` タグはタイトルと段落の間にある必要があります。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(code.match(/<\/h4>\s*?<hr(>|\s*?\/>)\s*?<p>/gi));
|
||
|
|
```
