Page Transitions and Adding a Back Button with WordPress Pages
If you are display a WordPress page, and you want a page transition when a link is clicked, add a class of 'push-page' to the link.
This will cause the page to have a back button.
<a href="http://mysite.com/page" class="push-page">Click here</a>
To add a link that gets rid of a stack of pages with back buttons, use the class .app-root-page. This is useful on the WooCommerce order confirmation page, so that your app user doesn't have to click back a bunch of times.
<a href="http://mysite.com/page" class="app-root-page">Click here</a>
