Getting familiar with the starter code

AMP boilerplate

An AMP page is an HTML page with some restrictions for reliable performance. AMP pages have a bit of special markup that identifies it as an AMP page.

A bare bones AMP page looks like this:

<!doctype html>
<html amp>
 <head>
   <meta charset="utf-8">
   <link rel="canonical" href="hello-world.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 src="https://cdn.ampproject.org/v0.js"></script>
 </head>
 <body>Hello World!</body>
</html>

AMP components

The tutorial's starter code (static/index.html) builds off the bare bones AMP page with its page content (images, text, etc.) as well as including a few AMP components:

<script async custom-element="amp-carousel" src="https://cdn.ampproject.org/v0/amp-carousel-0.1.js"></script>
<script async custom-template="amp-mustache" src="https://cdn.ampproject.org/v0/amp-mustache-0.1.js"></script>
<script async custom-element="amp-form" src="https://cdn.ampproject.org/v0/amp-form-0.1.js"></script>
<script async custom-element="amp-selector" src="https://cdn.ampproject.org/v0/amp-selector-0.1.js"></script>

AMP components offer additional functionality and UI components that add rich interactivity to AMP pages. The starter code uses the following AMP components:

  • amp-carousel: An image carousel that displays multiple views of the product.
  • amp-mustache: A templating system for rendering server responses from amp-form.
  • amp-form: Adds special functionality for <form> elements that are necessary for AMP pages.
  • amp-selector: Offers a semantic way to select one or many elements of a group of elements. Can be used as an input source to amp-form.

Basic interactivity

The starter code offers some basic interactivity:

  • The image carousel (an amp-carousel) displays multiple views of the product.
  • The product can be added to the user's cart (via amp-form) by tapping the "Add to cart" button on the bottom of the page.

Try it out: Swipe the image carousel and tap the "Add to cart" button.
