Approach looks good to me!

[jstoffan]

Each sub-component should have its own top-level class name, such as .bdl-MediaImage. It's probably fine for them to live in the same stylesheet, though, as long as re-importing it in each component doesn't create duplicate styles in the output CSS.

I was following this

https://github.com/suitcss/suit/blob/master/doc/naming-conventions.md#ComponentName-descendentName

[jstoffan]

That applies when different elements live in the same file, but since these are declared as separate components, they should be named as such.

[alexkrolick]

The sub-elements are meant to be used like Media.Body not as separate imports.

These are sub-elements almost exactly like the Tweet example in the SUIT docs.

Probably should check if https://github.com/box/box-ui-elements/blob/master/src/elements/content-sidebar/versions/VersionsItem.js can be refactored to use these components/design if possible

[alexkrolick]

I tested this out with the Activity Feed Comment/Task container and it seems to work. I'll put that out as a separate PR once this is in.

Nice job!
