There are existing docs about Hugo Syntax Highliting. They indicate that generating style sheets for syntax highlighting may be required but they don’t present a complete picture. This is an attempt to create that picture.
Changes to config.yaml
pygmentsCodefences: true
pygmentsCodefencesGuessSyntax: true
pygmentsStyle: "monokai"
Create a directory for the code highlighting css
mkdir static/css
Generate the syntax highlighting style sheet.
hugo gen chromastyles --style=monokai > static/css/syntax.css
