Font size too small: 0

I think maybe an error because pdf has more than 1 page and it creates all pages of pdf on 1 page

What I have tried:

string attachment = "attachment; filename=" + "abc" + ".pdf";
            Response.AddHeader("content-disposition", attachment);
            Response.ContentType = "application/pdf";
            StringWriter s_tw = new StringWriter();
            HtmlTextWriter h_textw = new HtmlTextWriter(s_tw);
            h_textw.AddStyleAttribute("font-size", "7pt");
            h_textw.AddStyleAttribute("color", "Black");
           this.Page.RenderControl(h_textw);//Name of the Panel
            Document doc = new Document();
            doc = new Document(PageSize.A4, 5, 5, 15, 5);
            FontFactory.GetFont("Times New Roman", 14);
            PdfWriter.GetInstance(doc, Response.OutputStream);
            StringReader s_tr = new StringReader(s_tw.ToString());
            HTMLWorker html_worker = new HTMLWorker(doc);
