Use the following code as a template for displaying a Google +1 button.

Default Google +1 button

<div class="a2a_kit a2a_default_style">
    <a class="a2a_button_google_plusone"></a>
</div>

<script type="text/javascript" src="http://static.addtoany.com/menu/page.js"></script>

Custom Google +1 button

Each Google +1 button is independently customizable by specifying any Google +1 button attribute as a data attribute. For example, you can change the size of the button to a tall (bubble) button, target a specific URL to share, and much more.

<div class="a2a_kit">
    <a class="a2a_button_google_plusone" data-href="http://example.com/" data-size="tall"></a>
</div>

<script type="text/javascript" src="http://static.addtoany.com/menu/page.js"></script>
