How to adjust the sidebar width

[niuzijia]

As shown in the figure, the width of the sidebar is too large, resulting in the width of the body being too small. How to modify the width of the sidebar to make the width of the body larger

this is my html_theme_options

html_theme_options = {
    "sidebar_hide_name": True,
    "light_logo": "logo-light.svg",
    "dark_logo": "logo-dark.svg",
    "light_css_variables": {
        "color-brand-primary": "black",
        "color-brand-content": "#28a745",
        "color-sidebar-caption-text": "#28a745",
        "sidebar-caption-font-size": "1.2em",
    },
    "dark_css_variables": {"color-brand-primary": "white"},
}

It is not possible to do so. The width of the body is limited so that text stays readable even on wide screens. See https://www.mediawiki.org/wiki/Reading/Web/Desktop_Improvements/Features/Limiting_content_width#Goals_and_Motivation for some discussion on why limiting the content width like that is a good thing for prose-heavy webpages.

@pradyunsg would you consider using the additional width on large screens to increase the width of the sidebars but not the body? See the following comparison (current one on the left, suggested on the right):

Raise this as a seperate discussion perhaps
