* 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).
