Break lines in blade translation files

use {!! !!} instead of {{ }} and <br/> tag in you message

<p>{!! trans('mission-vision-page.mission-description') !!}</p>

Add custom blade directive, in App\Providers\AppServiceProvider.php add:

\Blade::directive('lang2br', function ($expression) {
   return "<?php echo nl2br(app('translator')->getFromJson({$expression})); ?>";
});

Then you can use like lang directive:

@lang2br('something');
