Post/Page specific custom CSS will allow you to add cascade stylesheet to specific posts/pages. It will give you special area in the post/page edit field to attach your CSS. It will also let you decide if this CSS has to be added in multi-page/post view (like archive posts) or only in a single view.
You will see additional meta box below text input area on posts and pages screen. You may add whatever CSS you want. You may choose if you want to add this CSS code on certain single page/post or on pages like archive etc.

That’s all folks, have fun 🙂
Is it free?
Yes, it is under GPLv2 (and later) licence. However, you can donate me a few dollars if it makes you feel good. I certainly have nothing against it.
I am surprised this plugin is not more popular. It is a great way to add a little CSS to a page. Sometimes I just find it handy when I want to test CSS before adding it to my main stylesheet. Especially if I want to show someone global page changes before actually doing them globally.
Great plugin, exactly what I was looking for.
On my version (6.1.1) the CSS validation fails due to line 679 (there is no data object in wp object).const ppsccEditPost = wp.data.select('core/edit-post');
Otherwise the CSS saves and displays correctly.
I really loved your plugin but after installing WP 6.0 (PHP 7.4, WPML and TOTAL theme as Template) it crashed my site.

While it is a useful plugin, it does not wok in comments pagination. For example, you can use it to have custom CSS in a single page address: domain.com/title/ (custom css different from the general CSS of the whole site are used), but it does not work for comments pages of the same address such as:
As you know, there is no separate editing environment for comments pages. As a result, there is no separate box to add custom css for comments pages.
Suggestion for the next update: the plugin will be more useful if the custom CSS of each single page work for all of its comments pages (from first comments page to the last one).
