Blog Posts

Use amp-live-list to implement a live blog. The amp-live-list component regularly polls the host document for updated content and updates the end user's browser as new items become available. This means that every time a new post needs to be added, the host document should be updated by the CMS to include the update both the body and the metadata section. Find an amp-live-list example here.

Long blogs could use pagination to improve performance by limiting the number of blog items to be displayed on a page. To implement pagination, amp-live-list allows to add the <div pagination></div> element, to then insert any markup needed for pagination, for example the page number, a link to the next and previous page.

 
<amp-live-list class="live-list"
  layout="container"
  data-poll-interval="15000"
  data-max-items-per-page="5"
  id="amp-live-list-insert-blog">

  <button id="live-list-update-button"
    update
    on="tap:amp-live-list-insert-blog.update">You have updates</button>
  <div items>
    
  </div>
  <div pagination>
    <nav aria-label="amp live list pagination">
      <ul class="pagination">
        
        <li></li>
        
      </ul>
    </nav>
  </div>
</amp-live-list>
