I am using Laravel with DomPDF and it usually works well, but there is a case when it inserts blank pages (page after page), like pdf file, how to fix it pls.
I'm generating a pdf document using dompdf 0.6.0, and have a strange issue where a blank page is being created at the end. My (simplified) html:
<!doctype html>
<html lang="en">
<head>
<base href="{{ env('APP_URL') }}">
<meta name="csrf-token" content="{{ csrf_token() }}">
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<style>
.sheet {
position: relative;
}
.row{
clear: both;
display: block;
}
.item {
position: relative;
float: left;
display: inline;
width: {{ $output_width }}mm;
height: {{ $output_height }}mm;
}
.item img {
position: absolute;
width: 100%;
height: 100%;
}
.elm-serial,
.elm-username,
.elm-password {
position: absolute;
}
