Google AMP - Basic Syntax

Sample Amp Page

A basic example for an amp page is shown below −

<!doctype html>
<html amp>
   <head>
      <meta charset = "utf-8">
      <title>Amp Sample Page</title>
      <link rel = "canonical" href = "./regular-html-version.html">
      <meta name = "viewport" content = "width = device-width,
      minimum-scale = 1,initial-scale = 1">
      <style amp-custom>
         h1 {color: red}
      </style>
      
      <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 src = "https://cdn.ampproject.org/v0.js">
      </script>
   </head>
   <body>
      <h1>Amp Sample Page</h1>
      <p>
         <amp-img 
            src = "images/christmas1.jpg" 
            width = "300" 
            height = "300" 
            layout = "responsive">
         </amp-img>
      </p>
   </body>
</html>

Mandatory Tags

There are some mandatory tags to be included in a amp page. This section discusses them in detail −

We have to make sure that we add amp or ⚡ to the html tag as shown below

<html amp>
   OR 
<html ⚡>

We should add the <head> and <body> tags to the html page.

Amp validation may fail if you miss any of the mandatory meta tags. Some mandatory mets tags that are to be added head section of the page are shown here −

<meta charset="utf-8">
   <meta name  =  "viewport" 
      content = "width = device-width,
      minimum-scale = 1,
      initial-scale = 1">

Link of rel="canonical" to be added inside head tag

<link rel = "canonical" href = "./regular-html-version.html">

Style tag with amp-boilerplate −

<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 tag with amp-boilerplate −

<noscript>
   <style amp-boilerplate>
      body{
         -webkit-animation:none;
         -moz-animation:none;
         -ms-animation:none;
         animation:none}
   </style>
</noscript>

The amp script tag with async added to it as shown below. This is the most important tag of all −

<script async src = "https://cdn.ampproject.org/v0.js">
</script>

You should use this tag incase you want to add custom css to the page. Please make a note here we cannot call external style sheet in amp pages. To add custom css, all your css has to go here −

<style amp-custom>
   //all your styles here
</style>

You can validate the above page in your browser using #developement=1 at the end of the page-url.

Now, let us test the same in the browser. I have hosted the page locally and saved it as amppage.html.

The url for above to be tested is

http://localhost/googleamp/amppage.html#development=1

Example

<!doctype html>
<html amp>
   <head>
      <meta charset = "utf-8">
      <title>Amp Sample Page</title>
      <link rel = "canonical" href = "./regular-html-version.html">
      <meta name = "viewport" content = "width=device-width,
      minimum-scale = 1,initial-scale = 1">
      <style amp-custom>
         h1 {color: red}
      </style>
      <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}}@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 src = "https://cdn.ampproject.org/v0.js">
      </script>
   </head>
   <body>
      <h1>Amp Sample Page</h1>
      <p>
         <amp-img 
            src = "images/christmas1.jpg" 
            width = "300" 
            height = "250" 
            layout = "responsive">
         </amp-img>
      </p>
   </body>
</html>
