Google AMP - Fit Text

Quiz

Amp tag amp-fit-text will reduce the font-size, if the space is not sufficient to render the display. This chapter discusses this tag in detail.

To get amp-fit-text working, we need to add the following script −

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

Amp Fit-Text Tag

The format for amp-fit text tag is shown below −

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

Example

Let us understand this tag better with the help of an example.

<!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;-ms-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">

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

Output

The output of the code given above is as shown below −

If you see the display using amp-fit-text, the content tries to adjust as per the space available.

Amp-fit-text comes with 2 attributes max-font-size and min-font-size.

When we use max-font-size, and if the space is not available to render the text, it will try to reduce the size and adjust inside the space available.
Incase we specify min-font-size and if the space is not available it will truncate the text and show dots where the text is hidden.

Example

Let us see a working example where we will specify both max-font-size and min-font-size to amp-fit-text.

<html amp lang = "en">

      <style amp-boilerplate>

            -amp-start 8s steps(1,end) 0s 1 normal both;-ms-animation:
            -amp-start 8s steps(1,end) 0s 1 normal both;animation:
            -amp-start 8s steps(1,end) 0s 1 normal both
         }
