Rehype-wrap-all is an adaptation of Paul Zimmer rehype-wrap. It depends on a few great packages you should check out.
- hast-util-parse-selector - used to parse a selector into an element.
- hast-util-select - used to select an element to wrap.
- unist-util-visit - used to visit elements and their parent element.
