I like to make containers rounded edges

is there no anyway for all pages?

You can change:

.page-id-59 .inside-article,

to:

.page .inside-article,

not working David, I use this:

.page .inside-article, .single-post .inside-article, .generate-columns .inside-article, .widget, .wp-show-posts-inner {
border-radius: 20px;
overflow: hidden;
}

Hi Sabbir,

Can you share the link to a page in your site?

You may use the private information field for this: https://docs.generatepress.com/article/using-the-premium-support-forum/#private-information

How are you seeing it from your end? Viewing the site, I can see the CSS working.
