How to style answers from the Answers module to make them look as in the demo site?
First you should enable vote_up_down Field module too, so you can add it to your preferred content-type (e.g answers), while adding it, in settings it asks which kind of widget to use; set it as default, then it will be like in your picture, without any need of altering the used CSS styles. If you still dont get your desired look, it must be the CSS styles that are overwritten. Inspect the element, and look for it.
