Google AMP amp-sidebar用法及代码示例

边栏是Web页面中非常常见的函数，非常简单，但是用HTML CSS编写代码却很长。在AMP HTML中，我们使用amp-sidebar组件在页面上添加侧边栏。侧边栏提供对元内容的访问权限可以通过单击按钮来显示。

必需的脚本：将amp-sidebar组件导入标头。

HTML

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

属性：

side:指定侧边栏应从左侧或右侧弹出页面的哪一侧。保留其默认值。
layout:指定侧栏的布局，始终设置为nodisplay。
toolbar:此属性用于子<nav工具栏=“”>上，并接受媒体查询以在边栏中显示。
data-close-button-aria-label：指定按钮是否为aria-label。

例：

HTML
