Remove sidebar on post pages?

How can I remove the sidebar (and go full-width) on post pages? Like this one?

I’ve set “full width (no sidebar)”) in Appearance/Customize/Blog Options, but to no effect. Using “Masonry (no sidebar” doesn’t work, either.

There’s an older plugin,, that allows me to set post templates on a page-by-page basis. But it’s not being updated, and I’d like to make this a universal change across all posts.

Any help is appreciated!

Hi there,

You can achieve that with following custom css code:

body.single.single-post .widget-area {
    display: none;

body.single.single-post .content-area {
    width: 100%;

You can apply the code from child theme style.css file or use this plugin

Best Regards!

Works like a charm – thanks for the fast response!

You’re welcome,

And thank you for using our theme.

All the Best!

This was helpful, thanks!

It doesn’t work for me. Any ideas what’s going wrong?

Thank you so much
