Do you want help creating an Iframe? You should be able to find a tutorial. Otherwise, put the content you want to iframe in its own html file, then use <Iframe src="(yourfile)" width="width" height="height"></iframe>
First create a separate html file for the portion marked in red. Then in the main html file call that file <iframe src="(yourfilename)" width="width" height="height"></iframe> I think it should work...
