Pop up map content

Pop up map content

On a site I'm working on I have a map of Scotland with three towns highlighted. I want the user to be able to click on one of the towns and in front of the map a box pops up with information about the town. They then click to send the box away. I'm told jQuery is the best way to do this. I'm new to using jQuery so any help and advice anyone can give me would be good.

Thanks in advance, Iain.
