How to add a Tweet Button in WebHelp Responsive output using a publishing template

It is possible to integrate Twitter into your WebHelp Responsive output and you can specify where you want the widget to appear in your WebHelp page.

To add a Twitter™ Tweet widget to your WebHelp Responsive output using an oXygen Publishing Template, follow this procedure:

Go to the Tweet button generator page.
Fill-in the displayed form. The Preview and code area displays the code that you will need.

Copy the code snippet displayed in the Preview and code area and paste it into a div element inside an XML file called tweet-button.xml. Make sure you follow these rules:

The file must be well-formed.
The code for each script element must be included in an XML comment.
The start and end tags for the XML comment must be on a separate line.

The content of the XML file should look like this:

<div id="twitter">
  <a href="https://twitter.com/share" class="twitter-share-button">Tweet</a>
  <script>
  <!-- 
   !function (d, s, id) {
   var
   js, fjs = d.getElementsByTagName(s)[0], p = /^http:/.test(d.location)
? 'http': 'https';
   if (! d.getElementById(id)) {
   js = d.createElement(s);
   js.id = id;
   js.src = p + '://platform.twitter.com/widgets.js';
   fjs.parentNode.insertBefore(js, fjs);
   }
   }
   (document,
   'script', 'twitter-wjs');
  -->
</script>
</div>

Open the template descriptor file associated with your publishing template.

Use one of the parameters that begin with webhelp.fragment in the html-fragments section of the descriptor file. Set the value of that parameter to reference the tweet-button.xml file that you created earlier.

<publishing-template>
    ...
    <webhelp>
        ...                
      <html-fragments>
        <fragment 
         file="HTML-fragments/tweet-button.xml" 
         placeholder="webhelp.fragment.after.toc_or_tiles"/>
  </html-fragments>
</webhelp>
