    …e addtoany_special_service” data-href
   =”[http://itcsn.se/it_it/&#8221](http://itcsn.se/it_it/&#8221); ><a class=”…)
 * 2. (there is no attribute “data-annotation”
    …oany_special_service” data-annotation
   =”none” data-href=”[http://itcsn.se/it_it/…](http://itcsn.se/it_it/…))

 * Attributes for the 3rd party buttons (Tweet, Like, etc.) require a theme that
   uses an HTML5 doctype. You can either use a theme that supports HTML5, disable
   the 3rd party buttons, or live with minor validation errors.
 * I’d recommend switching from the 3rd party buttons to the standard AddToAny sharing
   icons for Facebook, Twitter, etc. These icons also load significantly faster 
   than their official counterparts (“3rd party buttons”).
