I meant to say that we can do a selector along the lines of `.oae-clip small`, so we don't have to add that class every time.

I think in general, we should avoid CSS styles that bind to structure, and should do id selectors if custom CSS properties will only be needed for that elements or a class selector if the custom CSS properties will be re-used multiple times. However, I think that's only true for HTML in widgets, pages, etc. In my mind, clips are a re-usable components with a fixed HTML structure that we want to easily re-use in multiple places. Therefore, we should make that HTML structure as clean as possible, reducing the chances of forgetting something and the HTML structure not working at all. That's why in this case I think it's actually better to add  things like float: right into the CSS properties, and not use the pull-right class.
