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

Answer 1

1. source\conf.py

html_theme = 'sphinx_rtd_theme'
html_style = 'css/my_theme.css'

2. source\_static\css\my_theme.css

@import url("theme.css");

.wy-nav-content {
    max-width: 90%;
}

That will be 90% width of your monitor.
