I am trying to change background color of the bar under profile picture on facebook (Wall, Informations, Photos etc.) with userscript.. I'm trying to do it like that but it's not working:
GM_addStyle("#uiSideNav uiSideNavSection uiFutureSideNavSection{ background-color:#ffffff; }");
Any ideas? thanks!
I'm not a big Facebook user, but the random wall pages I tested had no node with an id of uiSideNav.
Try a selector of .uiSideNavSection .uiFutureSideNavSection
-- which was present on the pages I sampled. So use:
GM_addStyle(".uiSideNavSection .uiFutureSideNavSection { background-color:#ffffff; }");
Note that you need the dots in front of the class names.
Also, for just style changes, the Stylish add-on is better and faster.
