What’s the correct way to add custom CSS safely in WordPress?

Asked on Aug 31, 2025

Answer

To add custom CSS safely in WordPress, you can use the built-in "Additional CSS" feature found in the Customizer, which allows you to apply styles without modifying theme files directly. This method ensures that your customizations are preserved even when the theme is updated.
  1. Log in to your WordPress dashboard.
  2. Navigate to Appearance → Customize.
  3. Select 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 "Additional CSS" feature is preferable to editing theme files directly, as it keeps your customizations safe during theme updates.
  • For more advanced users, consider creating a child theme to manage extensive CSS changes.
  • Always preview your changes before publishing to ensure they display as expected.
