I am having trouble trying to install and deploy iframe to my website with no CMS but only FTP file access and cPanel. 

For example, i want to display (actually still my website) login and register webpage from other domain i DONT have access to but hiding TOP LEFT HALF side of footer and ENTIRE footer. Also, after login and register, the member page content might be longer nad i am afraid the iFrame hider will block some of the contents. In other words, i don't know how to do the setting.

If you like to help me to do this, maybe i can pay you for the help. I will give my webpage html file and the other domain webpages i want to take from.
