Reviewing the starter code
Before we start adding code, let's review the sample article.amp.html page, which should be as follows:
<!DOCTYPE html>
<html ⚡ lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width" />
<link rel="canonical" href="/article.html" />
<link rel="shortcut icon" href="amp_favicon.png" />
<title>News Article</title>
<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>

This is a simple AMP page that passes both AMP validation and the schema.org structured data validation. If this page were deployed on a news website, users can discover the page through rich experiences in Search Engine Result Pages (e.g., the Top stories carousel in Google Search).
Enabling AMP Validator
Before we alter the page, let's enable the AMP validator so that we know we are working with valid AMP HTML. Add this fragment identifier to your URL:
#development=1
For example:
http://localhost:8000/article.amp.html#development=1
Open the Developer Console in Chrome (or your preferred browser), and verify there are no AMP errors.
- The AMP Validator extension for Chrome
- The AMP Validator extension for Opera
- The AMP Validator Web Interface
- ... and much more
Learn more in the Validate AMP pages guide.
Simulating the mobile experience
We're designing this page for a mobile device, so let's simulate the mobile device experience in your browser's developer tools. For example, in Chrome DevTools, click the mobile phone icon, and select a mobile device from the menu.
Now, we can start working on the page itself. Let’s add some AMP components to our page.
