WP Add Custom CSS allows you to add custom CSS to the whole website and to individual posts, pages and custom post types (such as Woocommerce products). 
The CSS rules applied to the whole website will override the default stylesheets of your theme and plugins, while the CSS rules applied to specific pages, posts or custom post types will override the main stylesheet too.
The plugin works with the most popular builders, such as Elementor, Gutenberg and the Classic Editor.
You can edit the main stylesheet from the the “Add custom CSS” settings page. 
The plugin also creates a new “Custom CSS” box in the editing area to add custom CSS to specific posts, pages and custom post types.
Select the preferred CSS output method from the plugin’s settings page to ensure seamless integration with caching and minification plugins or to improve above-the-fold rendering performance.

If you’ve ever wanted to control how a particular part of your page or posts looks without having to modify the theme files or stylesheets, 
this is a simple plugin that allows you to do that.
Once installed and activated, you’ll have a new settings panel in the WordPress admin that will provide you with a text area block 
where you can include any styling you’d like to use, and a second input field that allows you to insert a comma delimited list of page 
or post IDs to apply these styles to.
Alternatively, you can enter ‘ALL’, and have your styles applied on every page/post.
