# iOS 12 compatibility The backend detects iOS 12 in `resources/themes/backend/views/partials/head.blade.php` and adds an `ios12` class to ``. The compatibility rules are at the end of `resources/themes/backend/assets/css/helpdesk.css`. The iOS 12 dashboard deliberately uses flexbox instead of CSS Grid and uses inline SVG for critical shell/dashboard icons so it does not depend on modern Font Awesome webfont behaviour. Modern browsers continue to use the normal theme.
