Camelcase audit

[tbekolay]

Getting pretty nitpicky, but there are several places (CSS class names, yaml keys) where we use camelcase. Should it be hyphenated or snake cased or is camelcase preferred?

Related, we should probably start using a linter or formatter for files that have such tools available.

Personally I think that we should add prettier or something like that. This way we can set it and forget it.

Prettier or something similar that will work for markdown, yaml, scss etc sounds great to me
