Function html_to_styled 

pub fn html_to_styled(html: &str, style: DocStyle) -> StyledText

Parse an HTML fragment into a styled document.

A tag-soup reader, not a browser: it tracks the inline tags and inline style properties Day can express and ignores everything else, including <script>/<style> contents, which it skips wholesale. Unknown tags are transparent: their text survives, their meaning does not.
