MultiMarkDown 6 supports referencing a CSS in frontmatter e.g…

```markdown
---
css: “/Style Sheets/OMOS-KB.css”
---

```

However the new Markdown renderer doesn’t appear to support CSS in this way. Is this expected behaviour ? Choose between the new features and CSS?

There is no error in the rendering. The stylesheet shouldn’t be quoted and it should be URL-encoded, i.e., space is `%20`.

Also, YAML formatting isn’t required but can be used, depending on the need.

The upcoming maintenance release will support this syntax too.
