title: Dompdf style isn't working
body: <p>I'm trying to use dompdf, and even though my script generates a pdf document, the style tag doesn't work, here is my code. I understand how it works and already succesfully used it with only html, but it's the first time I use css and it doesn't work.  </p>
  
  <pre><code>    require_once 'dompdf/autoload.inc.php';
  ?&gt;
  &lt;?php
  
  $nom=$_GET['nom'];
  $prenom=$_GET['prenom'];
  $email=$_GET['email'];
  $numeroCommande=$_GET['numerocommande'];
  $commandeTotal=$_GET['commandeTotal'];?&gt;
  &lt;?php ob_start();?&gt;
  &lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;meta charset='utf-8'&gt;
  
      &lt;title&gt;Title&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;div class='invoice-box'&gt;
          &lt;table cellpadding='0' cellspacing='0'&gt;
              &lt;tr class='top'&gt;
                  &lt;td colspan='2'&gt;
                      &lt;table&gt;
                          &lt;tr&gt;
                              &lt;td class='title'&gt;
                                  &lt;img src='https://www.hollandbikes.com/img/holland-bikes-logo-1493142780.jpg' style='width:100%; max-width:300px;'&gt;

  <p>Do you have any idea why this tag isn't working? It's supposed to accept basic css, that's why I don't understand where the problem is. </p>
