问题描述
我正在使用 mPDF 将 HTML+css 内容添加到已生成/创建的 PDF。 HTML 内容已成功添加,但其中没有 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,即使我试图按照他们的文档中提到的那样导入它。这里有什么问题?
编辑:我什至在此处的 html 代码中添加了样式表,但它仍然不接受输入。

此进度条不会在 PDF 中生成。
解决方法
最好的解决方案是使用样式表。 请参见下面的示例:
<?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
希望它有效!!如果没有,请告诉我们我们在这里提供更多解决方案!!
