Its the instance versus the class value. If you add classes to the ‘classNames’ in the Class definition (i.e. the view directory) everytime you create a view it will have those classes in the beginning. (ex. sc-view).

Doing it in the main-page is an instance of the view so you can add custom class only for that particular instance of the view. Lets say you want a special styling for the first post on the page. This is where you would add that class. It won’t effect any other instances of the view.

What the difference in put ‘class-name’ in view ‘main-page’ and other specific view, as you have ‘another-custom-class’ and ‘title-view’ classes respectively.
