Google AMP - 自动调整文字大小

Amp 标签 amp-fit-text 如果空间不足以渲染显示，将减小字体大小。本章将详细讨论此标签。

要使 amp-fit-text 正常工作，我们需要添加以下脚本：

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

Amp 自动调整文字大小标签

amp-fit-text 标签的格式如下所示：

<amp-fit-text width = "200" height = "200" layout = "responsive">
   Text here 
</amp-fit-text>

示例

让我们通过一个例子更好地理解这个标签。

<!doctype html>
<html amp lang = "en">
   <head>
      <meta charset = "utf-8">
      <script async src = "https://cdn.ampproject.org/v0.js"></script>
      <title>Google AMP - Amp Fit-Text</title>
      <link rel = "canonical" href = "http://example.ampproject.org/article-metadata.html">
      <meta name = "viewport" content = "width = device-width,minimum-scale = 1,  initial-scale = 1">

      <style amp-boilerplate>
         body{
            -webkit-animation:-amp-start 8s steps(1,end) 
            0s 1 normal both;-moz-animation:

            -amp-start 8s steps(1,end) 0s 1 normal both;animation:
            -amp-start 8s steps(1,end) 0s 1 normal both
         }
         @-webkit-keyframes 
         -amp-start{from{visibility:hidden}to{visibility:visible}}@-moz-keyframes 
         -amp-start{from{visibility:hidden}to{visibility:visible}}@-ms-keyframes 
         -amp-start{from{visibility:hidden}to{visibility:visible}}@-o-keyframes 
         -amp-start{from{visibility:hidden}to{visibility:visible}}@keyframes 
         -amp-start{from{visibility:hidden}to{visibility:visible}}
      </style>
      <noscript>
         <style amp-boilerplate>
            body{
               -webkit-animation:none;-moz-animation:none;-ms
               -animation:none;animation:none}
         </style>
      </noscript>
      
      <script async custom-element = "amp-fit-text" 
         src = "https://cdn.ampproject.org/v0/amp-fit-text-0.1.js">
      </script>
   </head>
   <body>
      <h1>Google AMP - Amp Fit-Text</h1>
      <div style = "width:150px;height:150px; ">
         <amp-fit-text 
            width = "150"
            height = "150"
            layout = "responsive">
               
            <b>Welcome To TutorialsPoint - You are browsing the best resource

         </amp-fit-text>
      </div>
   </body>
</html>

输出

上面代码的输出如下所示：

如果您使用 amp-fit-text 查看显示，内容会尝试根据可用空间进行调整。

Amp-fit-text 带有两个属性 max-font-size 和 min-font-size。

当我们使用 max-font-size 时，如果空间不足以渲染文本，它将尝试减小大小并调整到可用空间内。
如果我们指定 min-font-size，并且空间不足，它将截断文本并在文本隐藏的地方显示点。

示例

让我们来看一个有效的例子，在这个例子中，我们将为 amp-fit-text 指定 max-font-size 和 min-font-size。
