WP Add Custom CSS and JS lets you add custom CSS and custom JavaScript to your WordPress website directly from the admin panel — without editing your theme, child theme, or plugin files. Write your code in a professional editor with syntax highlighting and autocomplete, and it is applied to your site instantly.
Add as many separate snippets as you want, manage them all from one screen, and decide exactly how and where each one loads. Every snippet can be automatically minified (compressed) so your custom code never slows your site down.
