Extended Markdown
This chapter briefly recapitulates the syntax for extended Markdown elements and shows their standard layout and alternative options.
PHP Markdown Extra and GitHub-flavored Markdown (GFM) introduced some widely used extensions to the CommonMark syntax. They are enabled by default in Hugo but we can disable them separately.
Hugo offers some additional extensions which are disabled by default and can be enabled separately. See the configuration file markup.yaml for this site.
Some extensions have already been mentioned:
- Linkify
- renders URLs in Markdown automatically into links — a quick and dirty way to reference URLs.
- Typographer
- substitutes ASCII punctuation characters with typographic characters. The substitution of quotation marks is a topic on the quote page.
