@khamudom let's set this to chore as these are not distributed. If we move these to a package to distribute at some point those can go in as a feature.

Disregard...versioning the site is likely fine.

Don't want to drag this PR out but I think the slot naming is confusing I propose this:

@eljefe223 is the proposal for everything to have a slot? Based on the current design of the site, I'm inclined to hold fast to to the fact that the Heading is the default thing you would likely want to pass here. I could see body copy being left off in some cases, or an action being left off in some cases. But something should always be the default and the intent of the design seems to be to introduce a section of content, which is why I would hold to the Heading being the default slot.

That's how it is currently. But the slots name don't match what I would expect them to do. Specifically the default slot being the top smaller heading and the badge slot being the large heading.

My thought is that we have the following named slots:

• badge
• body
• action

Default slot would be for Heading.
