8  Styling

Quarto has many styling options already in-built. Take a look at the HTML themes page and try out some existing themes!

It’s also possible to add your own styling, instead of, or additional to a Quarto theme. This can be done by adding a scss or css file to the repository and letting Quarto know to use it in the _quarto.yml:

format:
  html:
    css: styles.css

Here is a tutorial that introduces CSS.

Besides CSS or SCSS style sheets there is a lot that can also be customized in the _quarto.yml. Here you can find a lot of options for Quarto books and here for Quarto websites (which also largely work for Quarto HTML books).

This website with Quarto tricks is also very helpful in customizing Quarto content.
