So, here is my question. If you visit the link below and click on any of the shopping cart related buttons a windows pops up. But not a new window such as when you use target="_blank" attributes but a windows within your current window...
I need to know how to make these types of windows. Any help or a point in the right direction would really help. I don't even know what this type of function is called, as you can tell by my most likely very confusing description.
