Reply To: Empty sidebar shown on mobile

I can’t agree here. I tried hiding sidebar via plugin options, via adding CSS and via using a well respected plugin Widget Options (https://wordpress.org/plugins/widget-options/). None of these methods worked. I am still able to see the tab for empty sidebar. This is definitely a bug and should be adressed.
I can imagine a lot of situations when you want to hide some widget on mobile just because the screen is too small or you don’t want to overload CPU of smartphone with javascript etc. And currently this leads to poor user experience of having useless sidebar button with now widgets inside.
