Referencing the CSS file

Rather than adding styles to each Markdown file within the file, you can create and reference a Cascading Style Sheet (CSS) file each time you create a new file that contains particular styles and fonts.

In this exercise, the styles you've specified have been added to a CSS file called styles.css. You'll reference this file in the YAML header instead of specifying the styles within the Markdown file.

Exercise instructions

  • Add a css field to the YAML header after the html_document field before the toc field.
  • List the name of the CSS file, styles.css, that contains the styles you've specified for the Markdown file.
