html - Modifying content width of the Sphinx theme 'Read the Docs'

Question

I am using 'Read the Docs' Sphinx theme for my documentation. In the original theme, given below

http://read-the-docs.readthedocs.org/en/latest/theme.html

the content or main layout width is designed to be mobile friendly. However, for my project I would like this to be a bit more wide. I do not know HTML and hence would appreciate if any one could give me some clues to increase the content (layout) width.

Answer 1

Another option is to create a stylesheet in source/_static with just the css you want, e.g.

.wy-nav-content {
    max-width: none;
}

or

.wy-nav-content {
    max-width: 1200px !important;
}

Make sure the directory is referenced in source/conf.py - I believe by default there's a line to do this, i.e.

# Add any paths that contain custom static files (such as style sheets) here,
# relative to this directory. They are copied after the builtin static files,
# so a file named "default.css" will overwrite the builtin "default.css".
html_static_path = ['_static']

Then create a custom layout in source/_templates/layout.html and do something like this to include your stylesheet

{% extends "!layout.html" %}
{% block extrahead %}
    <link href="{{ pathto("_static/style.css", True) }}" rel="stylesheet" type="text/css">
{% endblock %}

Assuming you called your stylesheet style.css
