How to create Posts without sidebars?

Hello sturdy2,

I’m afraid that this is not what Custom Sidebars can do. Custom Sidebars allows to replace exiting sidebars with new ones and display those new ones depending on conditions you det for them.
It cannot create new sidebars or remove existing ones.
You could create empty sidebar and setup it for posts but this wouldn’t remove sidebar you already have.

In your case you would need to edit single.php template in your theme and remove sidebar code and then adjust looks with CSS – or use only CSS to hide sidebar. Whithout seeing your site I cannot provide whole CSS code, but it would look like that

.single #sidebar {display: none;}
.single #main-content {width: 100%;}

of course that code would need to be adjusted to your site markup. You can
a) add it to the child theme style.css file
b) use this small plugin https://www.ads-software.com/plugins/simple-custom-css/

kind regards,

Hi Kasia,

Not what I wanted to hear but thank you for your helpful response. There seems to be much confusion about this in the forums so I was unable to find an answer.

My best,
