Post/Page/Product-specific custom code allows you to add custom CSS styles to individual posts, pages, or WooCommerce products. It provides a dedicated area in the editor screen where you can write your CSS code. You can also choose whether the CSS should apply only to the single view or also to archive-type views.
A new meta box will appear below the content editor on the edit screen for posts, pages, and products. You can enter any custom CSS there and decide whether it loads only on the single view or also on archive pages like category listings or product grids.
This plugin requires at least WordPress 5.0 (remember always to keep your WordPress installation up to date!) and PHP 7.4 on your server.
Be warned! This plugin is a sneaky scam. Out of nowhere, a giant info box shoves a payment message in your face on the WordPress admin page. It’s clear the developer has no clue about user experience, and leaving their code on your site is a recipe for disaster.
Uninstalled. Spams the WP Admin page with money begs.
The CSS metabox has a spinner that continuously spin, and the CSS is now inject inside the BODY content of the page instead of the HEAD… probably another bug. Had to switch to Simple CSS. It inject the code in the header and minify it.
The plugin is very useful
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.
