Summary

Sample AMPHTML ad using amp-lightbox.

Styling

This is an advanced example that requires some styling to make it look and function properly. The styling designed here is responsive and will work with various ad sizes.

<style amp-custom>
  /* Main element that contains the creative. */
  .root-container {
    background: #000;
    color: #fff;

  /* Responsive styles so that the lightbox does not over-stretch */
  @media (max-height: 500px) {
    .lightbox {
      max-width: 400px;
    }
    .lightbox-hero {
      max-height: 160px;
    }
    .lightbox-hero-img {
      margin-top: -30px;
    }

  @media (max-height: 360px) {
    .lightbox-hero-img {
      display: none;
    }
    .lightbox-header {
      position: static;
    }
  }
</style>

amp-ad-banner is a dummy AMP element that is used by the AMP runtime to determine the position of the ad when a lightbox is opened.

Please note that amp-ad-banner is still in experimental stages and is likely to change in the future. See this GitHub issue for tracking.

<amp-ad-banner class="root-container"
  layout="container">

Cards

AMP has a system in place for events and actions. It uses a domain-specific language to describe how actions are triggered. In this example, we set the on attribute so the lightbox will activate when a card button is tapped.

Each button opens the lightbox related to the card that triggers it.

<div class="cards-container"
  id="cardsContainer">
  <div class="card card-seats">
    <div class="button expand-button"
      role="button"
      on="tap:lightbox-seats.activate">+</div>
    <amp-img src="/static/samples/img/car-seats.jpg"
      width="340"
      height="240"
      layout="responsive"
      alt="Ergonomic Leather Seats"></amp-img>
  </div>
</div>

Lightboxes

The amp-lightbox component defines the child elements that will be displayed in a full-viewport overlay. We set a different id for each lightbox so they can be opened and closed by actions on other elements. Its content is normal AMP HTML.

<amp-lightbox id="lightbox-seats"
  layout="nodisplay">
  <div class="lightbox">
    <div class="lightbox-hero">
      <amp-img src="/static/samples/img/car-seats.jpg"
        width="608"
        height="342"
        layout="responsive"
        alt="Ergonomic Leather Seats"
        class="lightbox-hero-img"></amp-img>
      <div class="lightbox-header">
        <amp-img src="/static/samples/img/car-logo.png"
          width="72"
          height="32"
          layout="fixed"
          alt="Howdy"
          class="logo-img"></amp-img>
        <h1>The all-new WX-S R5</h1>
      </div>
    </div>
    <div class="lightbox-main">
      <h3>Ergonomic Leather Seats</h3>
      <p>
        Available in Comfort Suede and leather. High-contrast stitching colors available.
      </p>
      <p class="learn-more">
        <a href="https://amp.dev/documentation/examples/"
          target="_blank">Learn more</a>
      </p>
    </div>
    <div class="lightbox-close-container">
      <div class="button lightbox-close-button"
        role="button"
        on="tap:lightbox-seats.close">
        Close
      </div>
    </div>
  </div>
</amp-lightbox>
