.. highlight:: python HTML theming support ==================== .. versionadded:: 0.6 Sphinx supports changing the appearance of its HTML output via *themes*. A theme is a collection of HTML templates, stylesheet(s) and other static files. Additionally, it has a configuration file which specifies from which theme to inherit, which highlighting style to use, and what options exist for customizing the theme's look and feel. Themes are meant to be project-unaware, so they can be used for different projects without change. Using a theme ------------- Using an existing theme is easy. If the theme is builtin to Sphinx, you only need to set the :confval:`html_theme` config value. With the :confval:`html_theme_options` config value you can set theme-specific options that change the look and feel. For example, you could have the following in your :file:`conf.py`:: html_theme = "classic" html_theme_options = { "rightsidebar": "true", "relbarbgcolor": "black" } That would give you the classic theme, but with a sidebar on the right side and a black background for the relation bar (the bar with the navigation links at the page's top and bottom). If the theme does not come with Sphinx, it can be in two static forms: either a directory (containing :file:`theme.conf` and other needed files), or a zip file with the same contents. Either of them must be put where Sphinx can find it; for this there is the config value :confval:`html_theme_path`. It gives a list of directories, relative to the directory containing :file:`conf.py`, that can contain theme directories or zip files. For example, if you have a theme in the file :file:`blue.zip`, you can put it right in the directory containing :file:`conf.py` and use this configuration:: html_theme = "blue" html_theme_path = ["."] The third form is a python package. If a theme you want to use is distributed as a python package, you can use it after installing .. code-block:: bash # installing theme package $ pip install sphinxjp.themes.dotted # use it in your conf.py html_theme = "dotted" .. _builtin-themes: Builtin themes -------------- .. cssclass:: longtable +--------------------+--------------------+ | **Theme overview** | | +--------------------+--------------------+ | |alabaster| | |classic| | | | | | *alabaster* | *classic* | +--------------------+--------------------+ | |sphinxdoc| | |scrolls| | | | | | *sphinxdoc* | *scrolls* | +--------------------+--------------------+ | |agogo| | |traditional| | | | | | *agogo* | *traditional* | +--------------------+--------------------+ | |nature| | |haiku| | | | | | *nature* | *haiku* | +--------------------+--------------------+ | |pyramid| | |bizstyle| | | | | | *pyramid* | *bizstyle* | +--------------------+--------------------+ .. |alabaster| image:: themes/alabaster.png .. |classic| image:: themes/classic.png .. |sphinxdoc| image:: themes/sphinxdoc.png .. |scrolls| image:: themes/scrolls.png .. |agogo| image:: themes/agogo.png .. |traditional| image:: themes/traditional.png .. |nature| image:: themes/nature.png .. |haiku| image:: themes/haiku.png .. |pyramid| image:: themes/pyramid.png .. |bizstyle| image:: themes/bizstyle.png Sphinx comes with a selection of themes to choose from. .. cssclass:: clear These themes are: * **basic** -- This is a basically unstyled layout used as the base for the other themes, and usable as the base for custom themes as well. The HTML contains all important elements like sidebar and relation bar. There are these options (which are inherited by the other themes): - **nosidebar** (true or false): Don't include the sidebar. Defaults to ``False``. - **sidebarwidth** (int or str): Width of the sidebar in pixels. This can be an int, which is interpreted as pixels or a valid CSS dimension string such as '70em' or '50%'. Defaults to 230 pixels. - **body_min_width** (int or str): Minimal width of the document body. This can be an int, which is interpreted as pixels or a valid CSS dimension string such as '70em' or '50%'. Use 0 if you don't want a width limit. Defaults may depend on the theme (often 450px). - **body_max_width** (int or str): Maximal width of the document body. This can be an int, which is interpreted as pixels or a valid CSS dimension string such as '70em' or '50%'. Use 'none' if you don't want a width limit. Defaults may depend on the theme (often 800px). * **alabaster** -- `Alabaster theme`_ is a modified "Kr" Sphinx theme from @kennethreitz (especially as used in his Requests project), which was itself originally based on @mitsuhiko's theme used for Flask & related projects. Check out at its `installation page`_ how to set up properly :confval:`html_sidebars` for its use. .. _Alabaster theme: https://pypi.org/project/alabaster/ .. _installation page: https://alabaster.readthedocs.io/en/latest/installation.html * **classic** -- This is the classic theme, which looks like `the Python 2 documentation `_. It can be customized via these options: - **rightsidebar** (true or false): Put the sidebar on the right side. Defaults to ``False``. - **stickysidebar** (true or false): Make the sidebar "fixed" so that it doesn't scroll out of view for long body content. This may not work well with all browsers. Defaults to ``False``. - **collapsiblesidebar** (true or false): Add an *experimental* JavaScript snippet that makes the sidebar collapsible via a button on its side. Defaults to ``False``. - **externalrefs** (true or false): Display external links differently from internal links. Defaults to ``False``. There are also various color and font options that can change the color scheme without having to write a custom stylesheet: - **footerbgcolor** (CSS color): Background color for the footer line. - **footertextcolor** (CSS color): Text color for the footer line. - **sidebarbgcolor** (CSS color): Background color for the sidebar. - **sidebarbtncolor** (CSS color): Background color for the sidebar collapse button (used when *collapsiblesidebar* is ``True``). - **sidebartextcolor** (CSS color): Text color for the sidebar. - **sidebarlinkcolor** (CSS color): Link color for the sidebar. - **relbarbgcolor** (CSS color): Background color for the relation bar. - **relbartextcolor** (CSS color): Text color for the relation bar. - **relbarlinkcolor** (CSS color): Link color for the relation bar. - **bgcolor** (CSS color): Body background color. - **textcolor** (CSS color): Body text color. - **linkcolor** (CSS color): Body link color. - **visitedlinkcolor** (CSS color): Body color for visited links. - **headbgcolor** (CSS color): Background color for headings. - **headtextcolor** (CSS color): Text color for headings. - **headlinkcolor** (CSS color): Link color for headings. - **codebgcolor** (CSS color): Background color for code blocks. - **codetextcolor** (CSS color): Default text color for code blocks, if not set differently by the highlighting style. - **bodyfont** (CSS font-family): Font for normal text. - **headfont** (CSS font-family): Font for headings. * **sphinxdoc** -- The theme originally used by this documentation. It features a sidebar on the right side. There are currently no options beyond *nosidebar* and *sidebarwidth*. .. note:: The Sphinx documentation now uses `an adjusted version of the sphinxdoc theme `_. * **scrolls** -- A more lightweight theme, based on `the Jinja documentation `_. The following color options are available: - **headerbordercolor** - **subheadlinecolor** - **linkcolor** - **visitedlinkcolor** - **admonitioncolor** * **agogo** -- A theme created by Andi Albrecht. The following options are supported: - **bodyfont** (CSS font family): Font for normal text. - **headerfont** (CSS font family): Font for headings. - **pagewidth** (CSS length): Width of the page content, default 70em. - **documentwidth** (CSS length): Width of the document (without sidebar), default 50em. - **sidebarwidth** (CSS length): Width of the sidebar, default 20em. - **bgcolor** (CSS color): Background color. - **headerbg** (CSS value for "background"): background for the header area, default a grayish gradient. - **footerbg** (CSS value for "background"): background for the footer area, default a light gray gradient. - **linkcolor** (CSS color): Body link color. - **headercolor1**, **headercolor2** (CSS color): colors for

and

headings. - **headerlinkcolor** (CSS color): Color for the backreference link in headings. - **textalign** (CSS *text-align* value): Text alignment for the body, default is ``justify``. * **nature** -- A greenish theme. There are currently no options beyond *nosidebar* and *sidebarwidth*. * **pyramid** -- A theme from the Pyramid web framework project, designed by Blaise Laflamme. There are currently no options beyond *nosidebar* and *sidebarwidth*. * **haiku** -- A theme without sidebar inspired by the `Haiku OS user guide `_. The following options are supported: - **full_logo** (true or false, default ``False``): If this is true, the header will only show the :confval:`html_logo`. Use this for large logos. If this is false, the logo (if present) will be shown floating right, and the documentation title will be put in the header. - **textcolor**, **headingcolor**, **linkcolor**, **visitedlinkcolor**, **hoverlinkcolor** (CSS colors): Colors for various body elements. * **traditional** -- A theme resembling the old Python documentation. There are currently no options beyond *nosidebar* and *sidebarwidth*. * **epub** -- A theme for the epub builder. This theme tries to save visual space which is a sparse resource on ebook readers. The following options are supported: - **relbar1** (true or false, default ``True``): If this is true, the `relbar1` block is inserted in the epub output, otherwise it is omitted. - **footer** (true or false, default ``True``): If this is true, the `footer` block is inserted in the epub output, otherwise it is omitted. - **bizstyle** -- A simple bluish theme. The following options are supported beyond *nosidebar* and *sidebarwidth*: - **rightsidebar** (true or false): Put the sidebar on the right side. Defaults to ``False``. .. versionadded:: 1.3 'alabaster', 'sphinx_rtd_theme' and 'bizstyle' theme. .. versionchanged:: 1.3 The 'default' theme has been renamed to 'classic'. 'default' is still available, however it will emit a notice that it is an alias for the new 'alabaster' theme. Creating themes --------------- As said, themes are either a directory or a zipfile (whose name is the theme name), containing the following: * A :file:`theme.conf` file, see below. * HTML templates, if needed. * A ``static/`` directory containing any static files that will be copied to the output static directory on build. These can be images, styles, script files. The :file:`theme.conf` file is in INI format [1]_ (readable by the standard Python :mod:`ConfigParser` module) and has the following structure: .. sourcecode:: ini [theme] inherit = base theme stylesheet = main CSS name pygments_style = stylename sidebars = localtoc.html, relations.html, sourcelink.html, searchbox.html [options] variable = default value * The **inherit** setting gives the name of a "base theme", or ``none``. The base theme will be used to locate missing templates (most themes will not have to supply most templates if they use ``basic`` as the base theme), its options will be inherited, and all of its static files will be used as well. * The **stylesheet** setting gives the name of a CSS file which will be referenced in the HTML header. If you need more than one CSS file, either include one from the other via CSS' ``@import``, or use a custom HTML template that adds ```` tags as necessary. Setting the :confval:`html_style` config value will override this setting. * The **pygments_style** setting gives the name of a Pygments style to use for highlighting. This can be overridden by the user in the :confval:`pygments_style` config value. * The **sidebars** setting gives the comma separated list of sidebar templates for constructing sidebars. This can be overridden by the user in the :confval:`html_sidebars` config value. * The **options** section contains pairs of variable names and default values. These options can be overridden by the user in :confval:`html_theme_options` and are accessible from all templates as ``theme_``. .. versionadded:: 1.7 sidebar settings .. _distribute-your-theme: Distribute your theme as a python package ----------------------------------------- As a way to distribute your theme, you can use python package. Python package brings to users easy setting up ways. To distribute your theme as a python package, please define an entry point called ``sphinx.html_themes`` in your setup.py file, and write a ``setup()`` function to register your themes using ``add_html_theme()`` API in it:: # 'setup.py' setup( ... entry_points = { 'sphinx.html_themes': [ 'name_of_theme = your_package', ] }, ... ) # 'your_package.py' from os import path def setup(app): app.add_html_theme('name_of_theme', path.abspath(path.dirname(__file__))) If your theme package contains two or more themes, please call ``add_html_theme()`` twice or more. .. versionadded:: 1.2 'sphinx_themes' entry_points feature. .. deprecated:: 1.6 ``sphinx_themes`` entry_points has been deprecated. .. versionadded:: 1.6 ``sphinx.html_themes`` entry_points feature. Templating ~~~~~~~~~~ The :doc:`guide to templating ` is helpful if you want to write your own templates. What is important to keep in mind is the order in which Sphinx searches for templates: * First, in the user's ``templates_path`` directories. * Then, in the selected theme. * Then, in its base theme, its base's base theme, etc. When extending a template in the base theme with the same name, use the theme name as an explicit directory: ``{% extends "basic/layout.html" %}``. From a user ``templates_path`` template, you can still use the "exclamation mark" syntax as described in the templating document. Static templates ~~~~~~~~~~~~~~~~ Since theme options are meant for the user to configure a theme more easily, without having to write a custom stylesheet, it is necessary to be able to template static files as well as HTML files. Therefore, Sphinx supports so-called "static templates", like this: If the name of a file in the ``static/`` directory of a theme (or in the user's static path, for that matter) ends with ``_t``, it will be processed by the template engine. The ``_t`` will be left from the final file name. For example, the *classic* theme has a file ``static/classic.css_t`` which uses templating to put the color options into the stylesheet. When a documentation is built with the classic theme, the output directory will contain a ``_static/classic.css`` file where all template tags have been processed. .. [1] It is not an executable Python file, as opposed to :file:`conf.py`, because that would pose an unnecessary security risk if themes are shared.
