You didn't get me. :/
I use only the right sidebar in homepage, and pages. I use both in all other page/post type.
I use a plugin to show the sidebar in certain page types. That's NOT the issue.
I want the footerbar to NOT shrink or get modified otherwise if the right sidebar is present. That's all I want.
I am using a child theme. You can easily figure that out.
the main thing here is:
.site-footer .widget-area (right sidebar inactive)
.sidebar.site-footer .widget-area (right sidebar active)
I already made it wider but somehow widgets aren't getting placed properly. That's where I need the help.
In addition, I'd also prefer the right sidebar to stay WITHIN its container. If the sidebar is long and post content is less, it overflows, messes up the footer. That's why footerbar gets shrunk in the first place.
I want to remove both of these default features of twenty thirteen.
