Docutils HTML writers

html

front-end:

rst2html

The writer name html is an alias for the default Docutils HTML writer.

The default may change with the development of HTML, browsers, Docutils, and the web. Currently, html is mapped to html4css1, it will become an alias for html5 in Docutils 2.0.

• Use get_writer_by_name('html') or the rst2html front end, if you want the output to be up-to-date automatically.

• Use a specific writer name or front end, if you depend on stability of the generated HTML code, e.g. because you use a custom style sheet or post-processing that may break otherwise.

html4css1

aliases:

html4, html

front-ends:

rst2html4, rst2html

config:

[html4css1 writer]

The HTML Writer module, docutils/writers/html4css1.py, was the first Docutils writer and up to release 0.13 the only official HTML writer.

The output conforms to the XHTML 1 Transitional specification. It does not validate as HTML 4.01 Transitional due to the closing of empty tags required in XML but not allowed in HTML 4. However, the output follows the HTML Compatibility Guidelines for proper rendering on most HTML user agents.

Correct rendering depends on a CSS style sheet. A reference style sheet, html4css1.css, is provided and used by default.

To support the Internet Explorer (with a market share of about 90% around 2002, the time this writer was written), documents contain some hard-coded formatting hints and are tagged as "text/html" (instead of "application/xhtml+xml"). [1]

html5

aliases:

html5_polyglot

front-end:

rst2html5

config:

[html5 writer]

The html5 writer generates polyglot HTML output, valid XML [2] that is compatible with HTML5. New features and elements are used if they are widely supported. See the HTML5 test page (and the sources html5-features.rst and html5-text-level-tags.rst) for further differences to the html4css1 writer.

There is no hard-coded formatting information in the HTML document. Correct rendering of elements not directly supported by HTML depends on a CSS style sheet. The provided style sheet minimal.css defines required styling rules; plain.css and responsive.css add optional rules for better legibility. Adaption of the layout is possible with custom style sheets. [2]
