Using a theme

Using an existing theme is easy. If the theme is builtin to Sphinx, you only need to set the html_theme config value. With the 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 conf.py:

html_theme = "default"
html_theme_options = {
    "rightsidebar": "true",
    "relbarbgcolor": "black"
}

That would give you the default 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 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 html_theme_path. It gives a list of directories, relative to the directory containing conf.py, that can contain theme directories or zip files. For example, if you have a theme in the file blue.zip, you can put it right in the directory containing conf.py and use this configuration:

html_theme = "blue"
html_theme_path = ["."]

The third form provides your theme path dynamically to Sphinx if the setuptools package is installed. You can provide an entry point section called sphinx_themes in your setup.py file and write a get_path function that has to return the directory with themes in it:

// in your 'setup.py'

setup(
    ...
    entry_points = {
        'sphinx_themes': [
            'path = your_package:get_path',
        ]
    },
    ...
)

// in 'your_package.py'

from os import path
package_dir = path.abspath(path.dirname(__file__))
template_path = path.join(package_dir, 'themes')

def get_path():
    return template_path

Builtin themes

Sphinx comes with a selection of themes to choose from.

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 (an integer): Width of the sidebar in pixels. (Do not include px in the value.) Defaults to 230 pixels.

• default – This is the default theme, which looks like the Python 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. Doesn’t work with “stickysidebar”. 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 used for this documentation. It features a sidebar on the right side. There are currently no options beyond nosidebar and sidebarwidth.

• 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 <h1> and <h2> 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 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 ommitted.

Creating themes

As said, themes are either a directory or a zipfile (whose name is the theme name), containing the following:

• A 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 theme.conf file is in INI format [1] (readable by the standard Python ConfigParser module) and has the following structure:

[theme]
inherit = base theme
stylesheet = main CSS name
pygments_style = stylename

[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 <link rel="stylesheet"> tags as necessary. Setting the 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 pygments_style config value.
• The options section contains pairs of variable names and default values. These options can be overridden by the user in html_theme_options and are accessible from all templates as theme_<name>.
