Page size doesn't work after auto setting pdf page height

Issue

I am generating pdf from html with 79mm width it is not working width:79mm

 <style type="text/css" media="print">
        @page {
            width: 79mm;
            page-break-inside: avoid;
        }
    </style>

and I am using with size so have to fix height then page breaks when dynamic values are more size: 79mm 250mm;

<style type="text/css" media="print">
        @page {
            size: 79mm 250mm;
                page-break-inside: avoid;
        }
    </style>

Solution

I have solved this problem by defining width and height in page size

@page {
        size: 79mm 270mm;
    }
