Google AMP amp-sidebar用法及代碼示例

邊欄是Web頁麵中非常常見的函數，非常簡單，但是用HTML CSS編寫代碼卻很長。在AMP HTML中，我們使用amp-sidebar組件在頁麵上添加側邊欄。側邊欄提供對元內容的訪問權限可以通過單擊按鈕來顯示。

必需的腳本：將amp-sidebar組件導入標頭。

HTML

<script async custom-element="amp-sidebar"
    src="https://cdn.ampproject.org/v0/amp-sidebar-0.1.js">
</script>

屬性：

side:指定側邊欄應從左側或右側彈出頁麵的哪一側。保留其默認值。
layout:指定側欄的布局，始終設置為nodisplay。
toolbar:此屬性用於子<nav工具欄=“”>上，並接受媒體查詢以在邊欄中顯示。
data-close-button-aria-label：指定按鈕是否為aria-label。
