/// Create a `Style` from `css`, rendering it to the DOM as a `<style>` in `<head>`.
/// The `css` is formatted, minfied, and small errors like invalid semi-colons can be
/// corrected, however invalid CSS itself is not handled by the parser.
///
/// Effects remain there order as defined, but their inner fields, as well as the Style's
/// fields will be ordered in a deterministic fashion to avoid duplication.
///
/// *Note*: Trailing semi-colons are required.
///
/// Returns error if missing access to: `Head`, `Crypto`(If generating a random ID),
