@kpodemski We didn't find any better solution for this usecase. So we decided to at least add classes like in the top cart summary here, so we can change it by JS.

Do you have any better names for the classes or it's ok?

@kpodemski adding classes at least is small thing and every theme should have classes for CSS targeting, so I think, this PR isn't problem .)
