           // plain + html -> <html><body><p>text1</p>text2</body></html>
           HtmlUtils.join("text1", "", "<html><body>text2</body></html>");
           // insert an empty paragraph (<p></p>) between two strings:
           HtmlUtils.join("text1", "", "text2");
           // this will insert two paragraphs:
           HtmlUtils.join("text1", "\n", "text2");

    Parameters:
      `texts` - either html (starting with <HTML> or <html>) or plain text.
