sphinx-panels

A sphinx extension for creating panels in a grid layout or as drop-downs.

  • The panels directive creates panels of content in a grid layout, utilising both the bootstrap 4 grid system, and cards layout.

  • The link-button directive creates a click-able button, linking to a URL or reference, and can also be used to make an entire panel click-able.

  • The dropdown directive creates toggle-able content.

  • The tabbed directive creates tabbed content.

  • opticon and fa roles allow for inline icons to be added.

Adaptive Sizing

Try shrinking the size of this window, to see how the panels above realign to compensate for small screens.

Installation

You can install sphinx-panels with pip:

pip install sphinx-panels

Sphinx Configuration

In your conf.py configuration file, simply add sphinx_panels to your extensions list, e.g.:

extensions = [
    ...
    'sphinx_panels'
    ...
]

This extension includes the bootstrap 4 CSS classes relevant to panels. They will be loaded by default but, if you are already using a bootstrap theme, you can disable this by adding panels_add_boostrap_css = False to your conf.py.

You can also change the delimiter regexes used by adding panel_delimiters to your conf.py, e.g. the default value (panels, header, footer) is:

panels_delimiters = (r"^\-{3,}$", r"^\^{3,}$", r"^\+{3,}$")

Panels Usage

Grid Layout

Panels are split by three or more - characters. The layout of panels is then set by using the bootstrap classes. Default classes for all panels may be set in the directive options, then panel specific classes can be added at the start of each panel.

By default the new classes will override those set previously (as defaults or in the top level options), but starting the option value with + will make the classes additive. For example the following options will set the first panel’s card to have both the shadow and bg-info classes:

.. panels::
    :card: shadow

    ---
    :card: + bg-info

Note

The default classes are:

.. panels::
    :container: container pb-4
    :column: col-lg-6 col-md-6 col-sm-6 col-xs-12 p-2
    :card: shadow
.. panels::
    :container: container-lg pb-3
    :column: col-lg-4 col-md-4 col-sm-6 col-xs-12 p-2

    panel1
    ---
    panel2
    ---
    panel3
    ---
    :column: col-lg-12 p-2
    panel4

panel1

panel2

panel3

panel4

Card Layout

Each panel contains a card, which can itself contain a header and/or footer, split by three or more ^^^ and +++ respectively.

Card Styling

To style the look of cards, you may use the directive options to add default CSS classes for each element, or use the per-panel option syntax to add to or override these:

  • container: the top-level container

  • column: the panel container

  • card: the panel card

  • body: the panel card

  • header: the panel header

  • footer: the panel footer

You can add your own CSS (see the html_css_files option) but it is advised you use the built-in bootstrap classes:

  • Card colouring contextual classes: bg-primary, bg-success, bg-info, bg-warning, bg-danger, bg-secondary`, ``bg-dark and bg-light.

  • Padding and margins: border-0, p-2, m-2, —

  • Text alignment: text-justify, text-left, text-center, text-right

.. panels::
    :body: bg-primary text-justify
    :header: text-center
    :footer: text-right

    ---
    :column: + p-1

    panel 1 header
    ^^^^^^^^^^^^^^

    panel 1 content

    ++++++++++++++
    panel 1 footer

    ---
    :column: + p-1 text-center border-0
    :body: bg-info
    :header: bg-success
    :footer: bg-secondary

    panel 2 header
    ^^^^^^^^^^^^^^

    panel 2 content

    ++++++++++++++
    panel 2 footer

panel 1 header

panel 1 content

panel 2 header

panel 2 content

Image Caps

Images can be added to the top and/or bottom of the panel. By default they will expand to fit the width of the card, but classes can also be used to add padding:

.. panels::
    :img-top-cls: pl-5 pr-5

    ---
    :img-top: _static/ebp-logo.png
    :img-bottom: _static/footer-banner.jpg

    header 1
    ^^^^^^^^

    Panel 1 content

    More **content**

    ++++++
    tail 1

    ---
    :img-top: _static/sphinx-logo.png
    :img-top-cls: + bg-success
    :img-bottom: _static/footer-banner.jpg

    header 2
    ^^^^^^^^

    Panel 2 content

    ++++++
    tail 1
img-top

header 1

Panel 1 content

img-bottom
img-top

header 2

Panel 2 content

img-bottom

Tabbed Content

The tabbed directive generates tabbed selection panels.

Sequential directives will be grouped together, unless the :new-group option is added. You can set which tab will be shown by default, using the :selected: option.

Tab directives can contain any content, and you can also set CSS classes with :class-label: and :class-content::

.. tabbed:: Tab 1

    Tab 1 content

.. tabbed:: Tab 2
    :class-content: pl-1 bg-primary

    Tab 2 content

.. tabbed:: Tab 3
    :new-group:

    .. code-block:: python

        import pip

.. tabbed:: Tab 4
    :selected:

    .. dropdown:: Nested Dropdown

        Some content

Tab 1 content

Tab 2 content

import pip

Here’s an example of showing an example in multiple programming languages:

int main(const int argc, const char **argv) {
  return 0;
}
def main():
    return
class Main {
    public static void main(String[] args) {
    }
}
function main()
end
PROGRAM main
END PROGRAM main

You can also control the colors of the labels and lines, setting panels_css_variables in your conf.py. Here are the defaults:

panels_css_variables = {
    "tabs-color-label-active": "hsla(231, 99%, 66%, 1)",
    "tabs-color-label-inactive": "rgba(178, 206, 245, 0.62)",
    "tabs-color-overline": "rgb(207, 236, 238)",
    "tabs-color-underline": "rgb(207, 236, 238)",
    "tabs-size-label": "1rem",
}

Note, the sphinx-tabs package also offers directives to create tabs. The key difference is that, whereas sphinx-tabs uses JavaScript to implement this functionality, sphinx-panels only uses CSS. A CSS only solution has the benefit of faster load-times, and working when JS is disabled, although JS allows sphinx-tabs to implement some extended functionality (like synchronized selections).

Inline Icons

Inline icons can be added to your text from either the GitHub octicon or FontAwesome libraries.

rST

Output

:opticon:`report`

:opticon:`x-circle,text-white bg-danger,size=24`

:fa:`save`

:fa:`spinner,text-white bg-primary fa-2x,style=fa`

Note that the theme you are using does not already include the FontAwesome CSS, it should be loaded in your conf.py, with the html_css_files option, e.g.:

html_css_files = ["https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css"]

By default, icons will only be output in HTML formats. But if you want fontawesome icons to be output on LaTeX, using the fontawesome package, you can add to your conf.py:

panels_add_fontawesome_latex = True

Additional classes can be added after a comma delimiter. Also the size (16px or 24px) can be set for opticons, and the style/prefix for fontawesome (version 5).

Div Directive

The div directive is the same as the container directive, but does not add a container class in HTML outputs, which is incompatible with Bootstrap CSS:

.. div:: text-primary

    hallo

hallo
