Migrate CSS Overrides
CSS selectors can change with updates to Lightning communities. If you plan to
continue using custom CSS overrides, migrate CSS selectors after you update the template.
- Use custom CSS sparingly since template updates don’t always support customizations.
- Custom CSS is 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.
