• The Content Editor Web Part is intended for adding HTML content to a Web Part Page, which may include hyperlinks. However, this Web Part is not designed to connect to a Web site. If you need to connect a Web Part to a Web site, consider using the Page Viewer Web Part.
• The Content Editor Web Part does not accept the HTML FORM element. If you need to add a Web Part that uses the FORM element, consider using the Page Viewer Web Part or the Form Web Part.
