Some care is taken to ensure that the IDs of the generated HTML elements (e.g., footnote references) are reproducible. In case the IDs vary across builds, it's a bug. Versions 4.1.x were supposed to implement this, but those releases were botched.

As of version 4.0.x

Altering variables org-html-checkbox-type and org-html-divs no longer has any effect. To provide default values for the corresponding options, use variables org-tufte-html-checkbox-type and org-tufte-html-sections respectively. The properties are still called :html-checkbox-type and :html-divs, however.
Similarly, HTML_DOCTYPE (as well, variable org-html-doctype and property :html-doctype) and HTML_CONTAINER (as well, variable org-html-container-element and property :html-container) keywords and html5-fancy option (as well, variable org-html-html5-fancy and property :html-html5-fancy) are disabled. Altering these values from the defaults is not supported.
The tufte-html backend definition makes explicit the options that it overrides compared to the html backend.
New command org-tufte-convert-region-to-html added.
Invoking org-export-string-as now works (#22).
Loading ox-tufte now advises org-export-as. For advanced uses, the depth of the installed advice is user-configurable via setopt (see org-tufte-export-as-advice-depth).

Introduction

Tufte CSS has visually appealing defaults for webpages and supports (among other things) margin and side notes. Unfortunately, Tufte CSS makes a number of demands of the HTML structure. This is a pity, because the HTML generated by ox-html breaks some of those assumptions (of tufte-css). Using ox-tufte you can avail the features of tufte-css when exporting an org-mode file to HTML. Since version 2+, the design goal of ox-tufte has been to minimally change the HTML structure generated by ox-html (with additional CSS as needed) to get behaviour that is equivalent to tufte-css.

ox-tufte tries very hard to not introduce additional constraints (over and above those imposed by ox-html and tufte-css) for users. In fact, work on ox-tufte version 2 began after noticing that:

ox-tufte was broken and didn't faithfully reproduce the tufte-css experience.
org-tufte made additional assumptions and was too opinionated. E.g.,
- deviations from ox-html
  - use of katex instead of mathjax
  - modified html-template
- automated inclusion of css hosted at third-party location

ox-tufte is still a work-in-progress, but it is being used by at least one blog in "production". Please open an issue if you discover any bugs!

Compatibility

Ox-tufte is compatible and tested with

tufte-css v1.8.0
org-mode >= 9.5
emacs >= 27.1

It's worth noting that Emacs 27.1 comes with Org version 9.3 (Org version 9.5 comes with Emacs 28.1), however, it can be updated via Emacs's "package menu" (M-x list-packages).

Please open issues if you discover any incompatibility!

Installation and Usage

You can install ox-tufte using MELPA:

(add-to-list 'package-archives
             '("melpa" . "http://melpa.org/packages/") t)

(package-refresh-contents)
(package-install 'ox-tufte)

And then in your init.el (or equivalent):

  (require 'ox-tufte)

It's important that you download tufte css (v1.8.0) and place it on your server (with the fonts).

Usage

The recommended way to use ox-tufte is with the default style provided by ox-html. Include tufte.css followed by src/ox-tufte.css (strictly in that order) in your org-mode document. This can be done by setting the :html-head option for ox-html. This can be done in elisp, or done in the specific org-mode document by adding a header such as:

  #+HTML_HEAD: <link rel="stylesheet" href="/path/to/tufte.css" type="text/css" />
  #+HTML_HEAD: <link rel="stylesheet" href="/path/to/ox-tufte.css" type="text/css" />

For usage, when exporting simply select "Tufte HTML" instead of regular HTML export from the export menu (C-c C-e).

Features

ox-tufte supports most of the features from tufte-css, some in different ways than expected, and some extensions.

Tufte-css concept	Org-mode syntax for tufte-css concept	ox-tufte extension
Sections and Headings	Sections and Headings
Sidenotes	Footnotes
Margin-notes	inline babel call to "marginnote" block	block margin-notes via "marginnote" special-block
Epigraphs	Quote block
iframe wrapper	"figure" org-mode special-block
Code	Source block
ImageQuilts	single image or images in"figure" special-block

Sidenotes and margin-notes

<<footnotes>>Org-mode footnotes become numbered Sidenotes from the tufte spec. The only limitation (inherited from tufte-css) is that a footnote can no longer include another footnote within.

Inline margin-notes

<<marginnotes-inline>>Since, Org-mode doesn't yet support syntax for inline special blocks (though it's being discussed and may be implemented in the near future), there are multiple ways to express inline margin-notes (i.e., margin-notes that can include HTML phrasing content). Inline margin-notes are implemented in their most feature-full incarnation as an inline babel call, specifically, to the "marginnote" block defined below.

If the only content of an inline margin-note is a link to an image, the generated HTML will be malformed. Use the zero width space escape character to communicate to the export process that the rendered image is to be contained within a paragraph. If you need to enforce a line break within the margin-note, use \\ at the end of a line as follows:

  This is some regular text call_marginnote("this will be a margin note") and some
  more text call_marginnote("another margin note.\\
  new line in second margin note.").

An alternative syntax of an inline margin-note as a macro is also provided with the following additional (wrt the inline babel call syntax) caveats:

macro invocations are not permitted in this syntax
commas need to be escaped with a backslash (\)
line breaks can be enforced by adding an unescaped comma

  This is some regular text {{{marginnote(this will be a margin note)}}} and some
  more text {{{marginnote(another margin note.,new line in second margin
  note.)}}}.

If, however, you only need an inline margin-note with some text without requiring specific control over line breaks or insertion of links or images (but still allowing for macro and babel call invocation), the margin-note-as-a-link syntax might be preferable.

The margin note number is optional and either `mn:1` or `mn:` as below would work:

  This is some regular text [[mn:1][this will be a margin note. while links aren't
  supported, commas don't need escaping.]] and some more text [[mn:][another margin note]].

The reason for not being able to insert links (or images) using this syntax is an org syntax limitation.

Block margin-notes

There is also support for "block" margin-notes, which are margin-notes that can contain "block" elements (HTML spec flow content) such as paragraphs, lists, tables etc. These are defined using an org-mode "marginnote" special-block (i.e., within #+begin_marginnote and #+end_marginnote, or within #+BEGIN_marginnote and #+END_marginnote).

  #+begin_marginnote
  This is a block level margin-note.
  - item 1
  - item 2
  #+end_marginnote

The block marginnote is displayed to the right side of the paragraph following it. In case a block margin-note is needed in the zeroth section (i.e., before the first heading in an org document), it needs to be wrapped within #+begin_zeroth-section and #+end_zeroth-section as follows:

  #+begin_zeroth-section
  #+begin_marginnote
  This is a block level margin-note.
  - item 1
  - item 2
  #+end_marginnote
  #+end_zeroth-section

<<epigraphs>>Epigraphs and quotes

Anything within #+begin_epigraph and #+end_epigraph becomes an epigraph (which is a collection of one or more quoted blocks). For example:

  #+begin_epigraph
  #+name: quote-1
  #+caption: Richard P. Feynman, @@html:<cite>“What Do You Care What Other People Think?”</cite>@@
  #+begin_quote
  For a successful technology, reality must take precedence over public relations,
  for Nature cannot be fooled.
  #+end_quote

  #+name: quote-2
  #+caption: Henri Matisse, @@html:<cite>Henri Matisse Dessins: thèmes et variations</cite>@@ (Paris, 1943), 37
  #+begin_quote
  I do not paint things, I paint only the differences between things.
  #+end_quote
  #+end_epigraph

ox-tufte also adds support for #+CAPTION on org-mode quote and verse blocks.

<<code>>Code

ox-tufte uses ox-html to export code fragments to HTML (without any alteration). ox-html and htmlize allow one to customize the syntax highlighting of the exported code blocks. An Emacs color theme that is visually consistent with tufte-css is the plan9-theme which can be installed from Melpa via something like:

  (add-to-list 'package-archives
               '("melpa" . "http://melpa.org/packages/") t)

  (package-refresh-contents)
  (package-install 'plan9-theme)

And then in your init.el or equivalent, load it using:

(load-theme 'plan9 t)

<<figures>>Figures and iframes

To use tufte-css's iframe-wrapper class, one can do something like below:

  #+ATTR_HTML: :class iframe-wrapper
  #+begin_figure
  @@html:<iframe width="853" height="480" src="https://www.youtube.com/embed/YslQ2625TR4" frameborder="0" allowfullscreen></iframe>@@
  #+end_figure

To have fullwidth figures:

  #+ATTR_HTML: :class fullwidth
  #+begin_figure
  #+CAPTION: Edward Tufte’s English translation of the Napoleon’s March data visualization. From Beautiful Evidence, page 122-124.
  [[https://edwardtufte.github.io/tufte-css/img/napoleons-march.png]]
  #+end_figure

Alternatively, the fullwidth class can also be applied to the image directly. However, in this case the resulting image may not truly be "fullwidth".

  #+ATTR_HTML: :class fullwidth
  #+CAPTION: Edward Tufte’s English translation of the Napoleon’s March data visualization. From Beautiful Evidence, page 122-124.
  [[https://edwardtufte.github.io/tufte-css/img/napoleons-march.png]]

Experiment and choose depending on your application.

<<quilts>>ImageQuilts

tufte-css has a notion of image quilts. the examples on tufte-css website are single images that were created by combining multiple images. However, that processing was done before linking via html. It's unclear what, if any, conveniences tufte-css provides for image quilts (over and above other features, since single images can already be included as desired).

However, in ox-tufte one can create a figure with multiple images.

  #+HTML_HEAD_EXTRA: <style> .quiltish img { max-height: 200px; min-height: 100px; } </style>
  #+attr_html: :class quiltish
  #+CAPTION: caption for multiple images
  #+begin_figure
  [[./path/to/img1.png]]
  [[./path/to/img2.png]]
  #+end_figure

Deviations and Extensions (from `tufte-css` and `ox-html`)

Sections and Headings

h4 heading level is supported in a consistent manner similar to h3.

Epigraphs

Epigraphs and quotes by default occupy only the width of the main content. In order to get quoted content that extends for the fullwidth add the fullwidth class with an #+attr_html annotation.

Sidenotes and margin-notes

tufte-css numbers sidenotes via CSS and as such referring to the same sidenote more than once results in erroneous numbering. ox-tufte fixes this.
Block margin-notes are supported via
```
#+begin_marginnote
```
and
```
#+end_marginnote
```
.

Figures

Captions on images are placed below the image (as opposed to in the margin area) regardless of whether the image is fullwidth or not.

Code

Since code blocks cannot have footnotes/sidenotes in them, they are treated as if they were using the "fullwidth" class (without having to specify the class via #+attr_html).

ImageQuilts

Unlike ox-html, in ox-tufte captions on figure special-blocks (the kind used when including multiple images in a block, as in ImageQuilts) are included as figcaptions. Limitation: presently the included caption doesn't include automated numbering.

Experimental

There may be some experimental extensions in src/ox-tufte-experimental.css. If desired, this css file should be included after src/ox-tufte.css.

Limitations

Incompatibility with `org-info.js`

The generated HTML is not compatible with org-info.js. This is because ox-tufte customizes the value of org-html-divs to align it with what's expected by tufte-css.

Code blocks are only fullwidth

Code blocks (multiline) currently behave only in a "fullwidth" manner. I.e., if there is sidenote content from previous paragraph, or a block margin-note it will push the code block down.

Constraints inherited from `tufte-css`

Additionally, ox-tufte presently inherits the following limitations from tufte-css:

Footnotes/sidenotes cannot contain nested footnotes/sidenotes.
Sidenotes cannot contain paragraphs, tables etc. (since they are HTML span elements).
Captions for iframe-wrapper blocks aren't supported.
The generated HTML must (and does) use an html5 doctype.

Incompatibility with `org-special-block-extras`

As of [2024-01-12 Fri], org-special-block-extras is incompatible with ox-tufte. As noted in this comment, the incompatibility is primarily due to hard-coded checks in org-special-block-extras which are too restrictive and need to be relaxed.

Customization

Footnotes section at bottom

The behaviour depends on the :footnotes-section-p option (which uses the value of org-tufte-include-footnotes-at-bottom as default).

Because footnotes are transformed to sidenotes they are currently hidden on very narrow screens (like phones), unless the use manually toggles visibility for each reference. if you want to include footnotes also at the bottom of the page, this may be set to t using setq:

  (require 'ox-tufte)
  (setq org-tufte-include-footnotes-at-bottom t)

Or, if you're using use-package:

  (use-package ox-tufte
    :config
    (setq org-tufte-include-footnotes-at-bottom t))

This behaviour can also be configured on a per-file basis using:

  #+OPTIONS: footnotes-section-p:t

Or, (assuming org-export-allow-bind-keywords is t) using below:

  #+BIND: org-tufte-include-footnotes-at-bottom t

Margin-note symbol and visibility on small screens

From tufte-css:

However, on small screens, a margin note is like a sidenote except its viewability-toggle is a symbol rather than a reference number. This document currently uses the symbol ⊕ (⊕), but it’s up to you.

This symbol can be tweaked, by modifying the value of org-tufte-margin-note-symbol. Specifically, if this value is set to the empty string (""), then margin-notes are always hidden on small screens.

Color of margin-note visibility-toggle and footnote-references

Margin-note visibility color toggle can be tweaked using something like

  label.margin-toggle {
      color: #a00000;
  }

For footnote references, something like below would work

  label.sidenote-number,
  .sidenote > sup.numeral {
      color: #a00000;
  }
