How to Create Countdown Timer for AMP Page for Blogger with CSS

Countdown Timer, usually displayed on a website, to mark the launch of an event. To display this countdown, Webmasters must create a JavaScript that uses timestamp, and is embedded in the Dom HTML of the website.

However, can a Countdown Timer be applied to an AMP page? Can Countdown be created without using JavaScript?

If without using JavaScript, of course it is not possible. For this reason, AMP-Project has prepared special AMP JavaScript elements that allow Webmasters to display Countdown on AMP HTML-based web pages.. 

amp-date-countdown

AMP Project has released a new element called amp-date-countdown, which allows Webmasters to create and display a Countdown Timer for their website needs.

To display it, Webmasters simply paste the amp-date-countdown element in the <head> tag, and can use amp-mustache to display it.

I will share a tutorial on How to make a Countdown Timer on an AMP HTML page complete with CSS to enhance its appearance. 

Create Countdown Timer for AMP Page

To create a Countdown Timer, you need to copy  amp-date-countdown and  amp-mustache element before </head>

<script async='' custom-element="amp-date-countdown" src="https://cdn.ampproject.org/v0/amp-date-countdown-0.1.js"></script>
  <script async='' custom-template="amp-mustache" src="https://cdn.ampproject.org/v0/amp-mustache-0.1.js"></script>

Then, copy the following code to the place you want. HTML code below will display the countdown automatically. 

<amp-date-countdown timestamp-seconds="1576225970" layout="fixed-height" height="200">
    <template type="amp-mustache">
    <div class='until'>
        We are Open in
        </div>
      <div id="timecontainer">
        <ul class='timediv'>
          <li class='time'>
        {{d}} days
          </li>
          <li class='time'>
          {{h}} hours
          </li>
          <li class='time'>
            {{m}} minutes</li>
          <li class='time'>
            {{s}} seconds
          </li>
        </ul>
      </div>
    </template>
  </amp-date-countdown>

You just need to change timestamp-seconds (yellow mark) that use to set the expiration this date countdown. Visit https://www.epochconverter.com/ to convert date to timestamp code. Then replace the yellow mark above with that timestamp.

To enhance the appearance, I have prepared this CSS, paste this CSS below among the amp-custom code:
amp-date-countdown {
      display: block;
    }
#timecontainer {
    background:#2c3e50;
    padding:10px;15px;
    display:block;
    text-align:center;
    font-size:24px;
    max-width:800px;
      margin:auto;
      width:100%;
  }
ul.timediv {
  list-style-type: none;
  margin: 0;
  padding: 0;
  overflow: hidden;
        color:#444;
}

li.time {
display:inline-block;
  padding:10px 15px;
  background:#f9f9f9;
  color:#000
}
