Text based document generation

Use the following command to create this document (slidy.html):

asciidoc slidy.txt

Press the Space key or the Left Arrow key to continue the slideshow.


AsciiDoc has a slidy backend for generating self contained Slidy HTML slideshows.

  • An overview of Slidy can be found here: https://www.w3.org/Talks/Tools/Slidy2

  • AsciiDoc ships with the Slidy JavaScript a customised Slidy CSS file.

  • Use the asciidoc --backend slidy command-line option to generate browser viewable HTML slideshow. Example:

    asciidoc --backend slidy slidy-example.txt
  • By default, asciidoc creates a self contained distributable HTML document which includes all necessary CSS and JavaScripts. Use the asciidoc --attribute linkcss command-line option if you prefer to link (rather than embed) external CSS and JavaScript files.

How Slidy uses AsciiDoc markup

  • The document header is displayed as the first page of the slideshow.

  • If the document has a preamble (the content between the header and the first section) it will be displayed on the second page.

  • Each top level section is displayed as a separate slide.

  • If the AsciiDoc incremental attribute is defined then all lists and OpenBlock elements are treated as incremental i.e. Slidy exposes their child elements one at a time as you progress through the slideshow.

  • You can explicitly set an element as incremental by setting its role attribute to incremental. Example:

    Sagittis in vestibulum. Habitasse ante nulla enim bibendum nulla.
    Odio sed pede litora.

Slidy Specific Attributes


If this attribute is defined then all lists and OpenBlock elements are classed as incremental i.e. Slidy will expose them one at a time as you progress through the slideshow. The default behavior is for the show to progress a full slide at at time. Elements that have been explicitly classed as incremental with the role attribute are always displayed incrementally.


Set this to the estimated number of minutes that your presentation will take and Slidy will display a countdown timer at the bottom right of the slideshow. For example, this asciidoc command-line option --attribute duration=5 sets the duration to five minutes.


If you set the copyright attribute it will be displayed in the Slidy menu bar at the bottom of the slide. If the copyright attribute is not define then the author name, if it is defined, will be displayed.


Setting the role attribute to outline in a bulleted or numbered list allows nested lists to be expanded and collapsed using the mouse. Nested lists are expanded when an enclosing list item (the ones with blue bullet points or numbers) is clicked.


  • slidy loads the asciidoc.css stylesheet followed by slidy.css:

    • asciidoc.css contains content presentational styles.

    • The customized slidy.css stylesheet contains Slidy specific styles (table of contents, menu and transition related).

  • You can use AsciiDoc CSS themes. For example, the asciidoc --attribute theme=volnitsky command-line option will substitute the asciidoc.css stylesheet for the distributed Volnitsky volnitsky.css stylesheet.

  • An additional stylesheet can be specified by setting the stylesheet attribute. For example, the --attribute stylesheet=myslidy.css will load myslidy.css after the standard CSS files.


  • The Slidy help? and contents? links at the bottom left are your friends.

  • Use the AsciiDoc data-uri attribute to embed images in your slideshow — add this attribute entry to your document’s header:

  • Use the AsciiDoc max-width attribute to set the document display width. For example, add this attribute entry to your document’s header:

    :max-width: 45em
