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>

Banner markup
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>
