-The `html` and `pdf` formats each provide an option or two. For example, for the HTML output we want the user to have control over whether to show or hide the code (`code-fold: true`) and use `katex` for math text. For PDF we define some margins. The `docx` format is a bit different---it specifies `docx: default`. This means just use all of the default options for the format.
