v0.1.6 be able to have mkt-prompt part of the page, html5 validation

Should this be renamed to mkt-form? 

**\<mkt-prompt\>**

I can either have one line of CSS here, or have over five if statements in Fireplace which is repeated code and multiple lines of compiled Nunjucks to JS. They don't have to add the button, this is for convenience. The use case isn't to switch from an on-page form to a modal, it's for code reuse between forms and modals. We have several pages (~5) in Fireplace where on mobile, they act as their own form on a separate page, and on desktop, they show up in a modal.

Oh, then I agree, I am changing to listen on types rather than positioning.
