Make it possible to style the label

[MarcSkovMadsen]

Its currently close to impossible to style the label because it has no class.

Please add a class name.

That would enable me to safely style the label for example as the "pills" shown below:

Its probably a good idea to systematically ensure any element has a class name enabling users to style it.
Maybe also to support label+title+action or other way of enabling multiple header elements like gradio daggr. Maybe that should be done via Panel component instead?
