Embed A Html In Pages


How do I embed an external HTML in pages? I am using the followng code with the cs-cart document page as an example, it seems like working in other HTML test but not in cs-cart pages, it shows a blank page.

       Your browser does not support frames. To wiew this page please use supporting browsers. 

Is cs-cart has any restriction in javascript embed in HTML? It seems like some HTML can view without any issue outside cs-cart but not in cs-cart pages.

Your help is very apprecaited.
