# --description--
|
||
|
||
Font Awesome 是一個非常便利的圖標庫。 這些圖標可以是網絡字體,也可以是一張矢量圖。 這些圖標就和字體一樣, 不僅能通過像素單位指定它們的大小,它們也同樣會繼承父級 HTML 元素的字號。
|
||
|
||
# --instructions--
|
||
|
||
爲 info 按鈕添加 Font Awesome `info-circle` 圖標,delete 按鈕添加 `trash` 圖標。
|
||
|
||
**注意:** 下述要求中的 `i` 元素也可以用 `span` 元素代替。
|
||
|
||
# --hints--
|
||
|
||
應在 `info` 按鈕元素中添加一個 `<i class="fas fa-info-circle"></i>`。
|
||
|
||
```js
|
||
assert(
|
||
$('.btn-info > i').is('.fas.fa-info-circle') ||
|
||
$('.btn-info > span').is('.fas.fa-info-circle')
|
||
);
|
||
```
|
||
|
||
應在 `delete` 按鈕元素中添加一個 `<i class="fas fa-trash"></i>`。
|
||
|
||
```js
|
||
assert(
|
||
$('.btn-danger > i').is('.fas.fa-trash') ||
|
||
$('.btn-danger > span').is('.fas.fa-trash')
|
||
);
|
||
```
|
||
|
||
每個 `i` 元素都應有一個閉合標籤,`<i class="fas fa-thumbs-up"></i>` 在 `like` 標籤元素中。
|
||
|
||
```js
|
||
assert(
|
||
code.match(/<\/i>|<\/span/g) &&
|
||
code.match(/<\/i|<\/span>/g).length > 2 &&
|
||
($('.btn-primary > i').is('.fas.fa-thumbs-up') ||
|
||
$('.btn-primary > span').is('.fas.fa-thumbs-up'))
|
||
);
|
||
```
