Migrate CSS Overrides

Many CSS selectors changed with the Lightning communities update. If you plan to continue using custom CSS overrides, migrate them forward after you update the template.
  • Use custom CSS sparingly because template updates might not support your customizations.
  • Custom CSS is now shared across all your community pages. If you used custom CSS for Login pages, copy it and close the CSS editor. Then navigate to a non-Login page, reopen the editor, and add the custom CSS.

Note

See each component’s documentation for a detailed list of all selectors.
