@Jess_Bromley, elm-ui seems to provide a really good ‘language’ to describe user interfaces.
This library is a complete alternative to HTML and CSS.
Sadly that’s too big a change for us right now, because it’s very compelling.
HTML semantics seem to embrace its “rose tree” format and always provide some meaning for the juxtaposition of siblings. elm-ui doesn’t seem to leave that meaning implicit and only defines it for elements that have the explicit purpose of combining elements, such as row. Interestingly, it does define Element.none, so Element msg seems to be a bit like Maybe (Html msg) (where Html has the usual definition).
