How do I add custom CSS safely in WordPress?

Asked on Oct 07, 2025

Answer

To add custom CSS safely in WordPress, you can use the built-in "Additional CSS" feature found in the WordPress Customizer. This method allows you to add custom styles without directly modifying theme files, ensuring your changes are preserved during theme updates.
  1. Log in to your WordPress dashboard.
  2. Navigate to Appearance → Customize.
  3. Click on the "Additional CSS" section.
  4. Add your custom CSS in the provided text area.
  5. Click "Publish" to save your changes.
Additional Comment:
  • Using the Customizer for CSS is safe as it doesn't alter theme files directly.
  • Consider using a child theme if you need to make extensive customizations beyond CSS.
  • For more advanced CSS management, plugins like "Simple Custom CSS" or "SiteOrigin CSS" can be used.
