pdf generation with Laravel

I'm using LynX39\LaraPdfMerger to generate my pdf files from a file named pdf.blade.php. When it's a normal html file everything seems to be good but once generate the pdf file everything is wrong and ugly. Is there any way to make the blade looks like the normal html file? You can see the 2 images below. Any help will be appreciated. Thanks.

to generate the file

$pdf = PDF::loadView('layouts.pdf_view', $data);
return $pdf->download('fiche' . '_' . time() . '.pdf');
