向mPDF添加html+css内容

Question

我使用mPDF将HTML+css内容添加到已生成/创建的PDF中。HTML内容已成功添加，但其中不存在css内容。也就是说，它应该显示一个圆形进度条(如下所示)，但不幸的是它没有生成它。我的假设是它不接受css输入，即使我试图像他们的文档中提到的那样导入它。这里的问题是什么？

编辑:我甚至在这里将样式表添加到html代码中，但它仍然不接受输入。

<?php
use setasign\Fpdi\Fpdi;

session_start();
ob_start();

require_once __DIR__ . '/vendor/autoload.php';

require_once('FPDI/autoload.php');
require_once('FPDI/Fpdi.php'); 

$pdf = new \Mpdf\Mpdf();

$pdf->AddPage(); 

$pdf->setSourceFile('file.pdf'); 

$tplIdx = $pdf->importPage(1); 

$pdf->useTemplate($tplIdx, 0, 0, 297, 420, true); 

$html = "

<style>
.flex-wrapper {
  display: flex;
  flex-flow: row nowrap;
}

.single-chart {
  width: 33%;
  justify-content: space-around;
}

.circular-chart {
  display: block;
  margin: 10px auto;
  max-width: 80%;
  max-height: 250px;
}

.circle-bg {
  fill: none;
  stroke: #eee;
  stroke-width: 3.8;
}

.circle {
  fill: none;
  stroke-width: 2.8;
  stroke-linecap: round;
}

.circular-chart.orange .circle {
  stroke: #ff9f00;
}

.percentage {
  fill: #666;
  font-family: sans-serif;
  font-size: 0.5em;
  text-anchor: middle;

</style>

    <div class='flex-wrapper'>
        <div class='single-chart'>

    </div>
</div>

";

$pdf->WriteHTML($html);

$pdf->Output("$file_new.pdf", "D");
ob_end_flush(); 
?>

在php标签之外，下面是分别给出的html和css代码：

​

.flex-wrapper {
  display: flex;
  flex-flow: row nowrap;
}

.single-chart {
  width: 33%;
  justify-content: space-around;
}

.circular-chart {
  display: block;
  margin: 10px auto;
  max-width: 80%;
  max-height: 250px;
}

.circle-bg {
  fill: none;
  stroke: #eee;
  stroke-width: 3.8;
}

.circle {
  fill: none;
  stroke-width: 2.8;
  stroke-linecap: round;
}

.circular-chart.orange .circle {
  stroke: #ff9f00;
}

.percentage {
  fill: #666;
  font-family: sans-serif;
  font-size: 0.5em;
  text-anchor: middle;
}

<div class="html-content">
    <div class="flex-wrapper">
        <div class="single-chart">
            <svg viewBox="0 0 36 36" class="circular-chart orange">
                <path class="circle-bg" d="M18 2.0845
          a 15.9155 15.9155 0 0 1 0 31.831
          a 15.9155 15.9155 0 0 1 0 -31.831" />
                <path class="circle" stroke-dasharray="56, 100" d="M18 2.0845
          a 15.9155 15.9155 0 0 1 0 31.831
          a 15.9155 15.9155 0 0 1 0 -31.831" />
                <text x="18" y="20.35" class="percentage">56%</text>
            </svg>
        </div>
    </div>
</div>

此进度条不会在PDF中生成。

最好的解决方案是使用样式表。如下例所示：

             <?php

             $html = $divPrint;

             include('mpdf.php'); // including mpdf.php
             $mpdf=new mPDF();
             $stylesheet = file_get_contents('pdf.css'); //this is ur external css
             $mpdf->WriteHTML($stylesheet,1);
             $mpdf->WriteHTML($html,2);
             $mpdf->Output();
             exit;

             ?>

在$mpdf中分配html，然后将其包含在mpdf.php文件中

希望它能工作！！如果没有，告诉我们我们在这里提供更多的解决方案！！
