# --description--

你可以用 `a`（Anchor，簡寫爲 a）來實現網頁間的跳轉。

`a` 需要一個 `href` 屬性指向跳轉的目的地。 同時，它還應有內容。 例如：

```html
<a href="https://freecodecamp.org">this links to freecodecamp.org</a>
```

瀏覽器將顯示文本 `this links to freecodecamp.org`，這是一個可點擊的鏈接。 你可以通過這個鏈接訪問 `https://www.freecodecamp.org`。

# --instructions--

創建一個內容文本爲 “cat photos” 的 `a` 元素，鏈接指向 `https://freecatphotoapp.com`。

# --hints--

`a` 元素應有錨文本 `cat photos`。

```js
assert(/cat photos/gi.test($('a').text()));
```

你的 `a` 元素應鏈接到 `https://freecatphotoapp.com`

```js
assert(/^https?:\/\/freecatphotoapp\.com\/?$/i.test($('a').attr('href')));
```

確保 `a` 元素有結束標籤。

```js
assert(
  code.match(/<\/a>/g) &&
    code.match(/<\/a>/g).length === code.match(/<a/g).length
);
```
