Google AMP - 自動調整文字大小

Amp 標籤 amp-fit-text 如果空間不足以渲染顯示，將減小字型大小。本章將詳細討論此標籤。

要使 amp-fit-text 正常工作，我們需要新增以下指令碼：

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

Amp 自動調整文字大小標籤

amp-fit-text 標籤的格式如下所示：

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

示例

讓我們透過一個例子更好地理解這個標籤。

<!doctype html>
<html amp lang = "en">

      <meta charset = "utf-8">
      <script async src = "https://cdn.ampproject.org/v0.js"></script>

         }

         -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">

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

輸出

上面程式碼的輸出如下所示：

如果您使用 amp-fit-text 檢視顯示，內容會嘗試根據可用空間進行調整。

Amp-fit-text 帶有兩個屬性 max-font-size 和 min-font-size。

當我們使用 max-font-size 時，如果空間不足以渲染文字，它將嘗試減小大小並調整到可用空間內。
如果我們指定 min-font-size，並且空間不足，它將截斷文字並在文字隱藏的地方顯示點。

示例

讓我們來看一個有效的例子，在這個例子中，我們將為 amp-fit-text 指定 max-font-size 和 min-font-size。
