What It Does

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 '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.
