Display Suite field content type class
Each time Display Suite is used in content output, it's wrapped in an &lt;article&gt; element with the content type as a class. You can see below that the content type can be found as node-enterprise-blog class.



I'm not sure what your end purpose for this is, but this way you can select the element using .node-enterprise-blog .field-field-name. If you need to add a class to the field, consider using the Field Template option under DS Extras. It allows you to change the markup of each field in a view mode.
