# 🏅 Day 17 - 偽元素

偽元素允許你在不改變 HTML 結構的情況下，在元素周圍添加額外的樣式，雖然能實現的樣式內容與元素本體相近，但卻是依附於元素本體的存在，無法獨立存在，因此被稱為偽元素。

### 常用偽元素
- ::before：在元素內容的前面插入一個偽元素。
- ::after：在元素內容的後面插入一個偽元素。

### 使用方式
使用 ::before 和 ::after 偽元素時，必須設定 content 屬性，即使值為空字串也要設定 `content: ""`。
偽元素預設為行內元素 (inline element)，若要設定寬高或進行區塊級排版，需要將其轉換為區塊或行內區塊元素。

### 範例
HTML

<p class="before-example">
  這段文字前面會多一個星號。
</p>

<p class="after-example">
  這段文字後面會多一個驚嘆號。
</p>

CSS

/* 用 ::before 在文字前面加東西 */
.before-example::before {
  content: "★"; /* 在內容前面加一個星號 */
  color: gold;
}

/* 用 ::after 在文字後面加東西 */
.after-example::after {
  content: "！"; /* 在內容後面加一個驚嘆號 */
  color: red;
}
