How to change background color of specific pages or page content

Hi,

Unfortunately to set the background color on specific/one post, this is possible only with custom css.
In order to do that you need to get the post id, just go in post and hover the title post https://www.screencast.com/t/5Cf6BVDe

the custom css is :
.postid-8197 .post{
background-color: lightgray;
}
.postid-8197 .tdc-row{
background-color: white;
}

for page
.page-id-2554 .td-main-page-wrap {
background-color: red;
}

Or you can set background color on categories -> https://forum.tagdiv.com/primary-category/
You need to paste the css in Newspaper>Theme panel>Custom code>Custom css
Hope this will help you.

Thank you for your understanding.
