/*
* sidebar.js
* ~~~~~~~~~~
*
* This script makes the Sphinx sidebar collapsible.
*
* .sphinxsidebar contains .sphinxsidebarwrapper. This script adds
* in .sphixsidebar, after .sphinxsidebarwrapper, the #sidebarbutton
* used to collapse and expand the sidebar.
*
* When the sidebar is collapsed the .sphinxsidebarwrapper is hidden
* and the width of the sidebar and the margin-left of the document
* are decreased. When the sidebar is expanded the opposite happens.
* This script saves a per-browser/per-session cookie used to
* remember the position of the sidebar among the pages.
* Once the browser is closed the cookie is deleted and the position
* reset to the default (expanded).
*
* :copyright: Copyright 2007-2023 by the Sphinx team, see AUTHORS.
* :license: BSD, see LICENSE for details.
