Add hovercards to Google+ profile links on your website or blog

As long as your web page calls the Google+ platform js file (which it does if it has a +1 button), you can add a hovercard to any Google+ profile link by adding:

class="g-profile"

to the link HTML.

Add hover cards to any web page.

To add +Google+ hover cards to any web page just add the class "g-profile" to any profile links you include in your web page.

The hover cards should work as long as the page calls the platform js file, which your site will already be doing if the site uses any Google+ feature, such as the plus one button.
