Custom CSS

If you are not satisfied with the CSS styles provided by nbsphinx and by your Sphinx theme, don't worry, you can add your own styles easily.

For All Pages

Just create your own CSS file, e.g. my-own-style.css, and put it into the _static/ sub-directory of your source directory.

You'll also have to set the config values html_static_path and html_css_files in your conf.py, e.g. like this:

html_static_path = ['_static']
html_css_files = ['my-own-style.css']

For All RST files

If you want your style to only apply to *.rst files (and not Jupyter notebooks or other source files), you can use rst_prolog with the raw directive in your conf.py like this:

rst_prolog = """
.. raw:: html

    <style>
        h1 {
            color: fuchsia;
        }
    </style>
"""

For All Notebooks

Similarly, if you want your style to only apply to notebooks, you can use nbsphinx_prolog like this:

nbsphinx_prolog = """
.. raw:: html

    <style>
        h1 {
            color: chartreuse;
        }
    </style>
"""

For a Single Notebook

For styles that should affect only the current notebook, you can simply insert <style> tags into Markdown cells like this:

<style>
    .nbinput .prompt,
    .nboutput .prompt {
        display: none;
    }
</style>

This CSS example removes the input and output prompts from code cells, see the following cell:
