Chunk options using comment-pipe syntax

Note

About this example

In this example, we are presenting how to pass options to cells that does not use the # as comment character.

This will be blue

In this document we have added the following css chunk known by the knitr engine

```{css}
/*| echo: false */
h2 {
  color: blue;
}
```

By default, it is echo: true but we can pass some chunk option by using the language comment syntax (/* and */ here for CSS), appending pipe character | after start comment. This is how we set the configuration to be echo: false and not show the content in the output document.

Quarto is aware about comments character(s) for a number of language.
