add to widget

The AddToAny plugin has its own WordPress Widget called “AddToAny Share.” If you’re instead looking to put the [addtoany] shortcode within a widget, some additional plugin might enable that functionality.

Your theme is overriding the default CSS alignment and styling. Generally, it’s best to use AddToAny’s “Large” or “Custom” icons instead of the “Small” size, and to avoid using the Like/Tweet/etc. buttons because there are notorious for alignment issues.
