Can you please try to use the below sample code snippet in order to add the HTML string in the PDF Page Header and let us know in case you still face any issue:

[C#]

Document doc = new Document();
doc.Pages.Add();

HtmlFragment htf = new HtmlFragment("<span style='color: #ff0000; white-space: nowrap; -ms-writing-mode: tb-rl; transform: rotate(180deg); background-color: #ffff00; -webkit-writing-mode: vertical-rl;'>123456</span>");
HeaderFooter header = new HeaderFooter();
header.Paragraphs.Add(htf);
doc.Pages[1].Header = header;
doc.Save(dataDir + "HTMLInHeader.pdf");

Please make sure that you are using Aspose.PDF for .NET 21.3. In case you are using other Aspose APIs as well, you can initialize HeaderFooter Class with full namespace like Aspose.Pdf.HeaderFooter. Please share a sample application for our reference in case issue still persists. We will again test the scenario in our environment and address it accordingly.
