hyperlink

问题 I read this (1) and this (2) but I'd like to have a simple method to do that... and that works! Both ( (1) and (2) ) does not works for me.

问题 Is it possible to load an external website into my own existing page? Or, is this a security risk, and will it not be allowed, or is it too uncommon and a burden to accomplish?

问题 I found this script to change the body's background image when you click a link.
