# --description--

|
與 `header` 和 `nav` 類似，`footer` 元素也具有語義化的特性，可以讓輔助工具快速定位到它。 它位於頁面底部，用於呈現版權信息或者相關文檔鏈接。
|
||
|
|
|
||
|
|

Camper Cat 的忍者訓練頁面進展順利。 請將他在頁面底部呈現版權信息的 `div` 元素更改爲 `footer` 元素。
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
應存在一個 `footer` 標籤。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert($('footer').length == 1);
|
||
|
|
```
|
||
|
|
|
||
|
|
不應存在 `div` 標籤。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert($('div').length == 0);
|
||
|
|
```
|
||
|
|
|
||
|
|
確保 `footer` 元素有結束標籤。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(code.match(/<footer>\s*© 2018 Camper Cat\s*<\/footer>/g));
|
||
|
|
```
