I run php artisan make:auth
command in laravel 5.3, it generates the scaffolding for me but the view styles are missing.
Login and registered views are not styles, they are just simple html.
Double check source code if the styles links are linked correctly or not ?
Check views code and in there check for the link and script tags . You should use something like this to link the css and scripts etc
{{ url('styles.css') }}
It will grab the styles from your app public directory.
