Migrate CSS Overrides

Between Spring ’17 and Winter ’19, the CSS selectors of several Experience Builder components were updated. If you haven’t updated your template since then, and your site uses custom CSS to override the default template and Theme panel styles, you must migrate to the new selectors.

See Update Your Experience Builder Template in Salesforce Help.

  • Use custom CSS sparingly since template updates don’t always support customizations.
  • Custom CSS is now shared across all your site 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.
