Answer 1

Create it with 0 margins or whatever you'd like accordingly
$mpdf=new mPDF('utf-8', 'Letter', 0, '', 0, 0, 0, 0, 0, 0);
class mPDF ([ string $mode [, mixed $format [, float $default_font_size [, string $default_font [, float $margin_left , float $margin_right , float $margin_top , float $margin_bottom , float $margin_header , float $margin_footer [, string $orientation ]]]]]])

Answer 2

mpdf page layout can be customize with the following approach
For mpdf version 6.0 we can use
$mpdf=new mPDF('utf-8', 'A4', 0, '', 0, 0, 0, 0, 0, 'L'); // use this customization
The default settings of mPDf in version 6.0 along with the parameters looks like
function mPDF($mode='',$format='A4',$default_font_size=0,$default_font='',$mgl=15,$mgr=15,$mgt=16,$mgb=16,$mgh=9,$mgf=9, $orientation='P')
For mpdf version 7.0 or greater we can use
$mpdf= new \Mpdf\Mpdf(['mode' => 'utf-8','format' => 'A4','margin_left' => 0,'margin_right' => 0,'margin_top' => 0,'margin_bottom' => 0,'margin_header' => 0,'margin_footer' => 0]); //use this customization
The default settings of mPDf in version 7.0 along with the parameters looks like
$constructor = [
'mode' => '',
'format' => 'A4',
'default_font_size' => 0,
'default_font' => '',
'margin_left' => 15,
'margin_right' => 15,
'margin_top' => 16,
'margin_bottom' => 16,
'margin_header' => 9,
'margin_footer' => 9,
'orientation' => 'P',
];
Futher detail regarding the available options of mPDF class can be get from the official documentaion https://mpdf.github.io/reference/mpdf-functions/construct.html

You can adjust the margins using by setting parameters as below
new Pdf([
'mode' => '', // leaner size using standard fonts
'format' => Pdf::FORMAT_A4,
'orientation' => Pdf::ORIENT_LANDSCAPE,
'marginTop' => 0,
'marginBottom' => 0,
'marginLeft' => 0,
'marginRight' => 0,
'destination' => Pdf::DEST_BROWSER,
'content' => $this->renderPartial('certificate_pdf', ['']),
'options' => [
// any mpdf options you wish to set
],
'methods' => [
'SetTitle' => '',
'SetSubject' => '',
'SetHeader' => [''],
'SetFooter' => [''],
'SetAuthor' => 'Ajira Tracking',
'SetCreator' => 'Ajira Tracking',
'SetKeywords' => 'Ajira Tracking',
]
]);
