I assume you are using the default theme 'PatternSkin'
One Example of modifying the Sidebar is to change the width:
to do this create a attachment 'SidebarCustomWidth.css' with the following css
#patternOuter {
margin-left: 8em;
}
#patternSideBar {
width: 8em;
margin-left: -8em;
/*background-color: rgb(200, 200, 255);*/
}
/* remove padding */
#patternSideBarContents {
padding-right: 0;
padding-left: 0;
}
then you can use it with
* Set USERSTYLEURL = %PUBURLPATH{topic="TheWebname.TopicWithAttachment" "SidebarCustomWidth.css"}%
you can find this example at

and some more Documentation and Examples at

Other Options to customize the Content of the Sidebar can be found at
https://foswiki.org/System/PatternSkin#Top_44_Bottom_and_Left_Bar_customization
regarding the Sidebar you can look for WebLeftBar
.
every web has its own Topic WebLeftBar
. you can change this to your needs. If a Web has no WebLeftBar
Topic and no WebLeftBarExample
Topic (thats the fallback) the Sidebar does not render.
if you want to change the defaults for new webs you can do this in the _default
web.
