Google AMP amp-anim用法及代码示例

如果要在AMP网页上嵌入动画，则可以使用此标记。它可以帮助开发人员将动画，gif，webp等嵌入到您的Web平台中。这确实是一个非常有用的标记，因为在您的网站上制作动画确实使其变得俗气且good-looking。

设置：

要在AMP网页中使用amp-anim，您必须导入此脚本。

HTML

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

在大多数方面，它类似于amp-img。

例：

HTML

<!doctype html> 
<html amp> 
  
<head> 
    <meta charset="utf-8"> 
  
    <title>Google AMP amp-anim</title>
