How to find selectors for customizing

I like to customize something in the Latest Blog Module and read the section "Template CSS Overrides" in http://stackideas.com/docs/easyblog/administrators/customizations/template-overriding. All is clear and simple and complies the standards. But where can I see how the classes and id's are named? For example: I like to customize the text. In the source view of the website I can see the class is "eb-mod-body", but I don't know the rest of it.
