34 Use Shortcodes

Shortcodes are small blocks of square-bracketed code which Pressbooks recognizes and handles in special ways in the webbook and export files. Shortcodes can be used both in the Visual Editor and in the Text editor. For most users, inserting content via the Visual Editor will be the easiest option. Shortcodes also provide a convenient way to include Pressbooks-specific elements in an external document which is intended for import into Pressbooks.

Note: Shortcode examples on this page are wrapped in a <code> element which forces the shortcodes to be displayed as text instead of being properly rendered. If you paste them from this chapter into your book, they will not work correctly. You can, however, retype the text displayed in the shortcode into your chapter.

Headings and subheadings

[heading]Top-level heading inside chapter (H1)[/heading]
[subheading]Second-level heading inside chapter (H2)[/subheading]

Description: Formats the text as a heading (h1) or subheading (h2). Note that the “heading” is not the chapter title, but the next level of headings. Custom classes can be applied to this shortcode.

Example Code Example Output

Code

[code]Text to be rendered in fixed-width font.[/code]

Description: Formats the text with fixed-width font. HTML tags can be displayed if they are entered in the visual editor (Pressbooks will automatically convert them to HTML character entities). Custom classes can be applied to this shortcode.

Nesting Shortcodes

The following shortcodes can be nested within other shortcodes:

  • [latex][/latex] shortcodes can be used inside of [footnote] and [blockquote] shortcodes
  • [media] shortcodes can be used inside of [glossary] shortcodes
  • [footnote] shortcodes can be used inside of [textbox] shortcodes

All shortcodes except for footnotes, glossary terms, and captions have an alternate styling method available from the visual editor toolbar, which should help you avoid nesting unsupported shortcodes within each other.
