i would like to ask you if is there any way to hide sidebar when there is no widget .
I noted that in some themes, when I remove all widgets from the sidebar (Apparence -> Widgets), the sidebar disappear from the site and the content become 100% width. I want this!
But in some themes, even when I remove all widgets, it shows default widgets in the sidebar instead of hide it.
How to hide the sidebar when there is no widget? And let the content 100% width.
