Markup
The overlay is an absolutely positioned div
that sits on top of the amp-video
element and fills the parent player container. It hosts the poster image, video title and a play icon.
Play icon uses play
and hide
AMP actions to hide the overlay and play the video when it is tapped.
<div class="video-player">
<amp-video id="myVideo" controls width="1280" height="720" layout="responsive" src="/static/samples/video/bullfinch.mp4">
</amp-video>
<div id="myOverlay" class="click-to-play-overlay">
<h3 class="video-title">Title of the video</h3>
<div class="play-icon" role="button" tabindex="0" on="tap:myOverlay.hide, myVideo.play"></div>
<amp-img class="poster-image" layout="fill" src="/static/samples/img/bullfinch_poster.jpg"></amp-img>
</div>
</div>
