Question: I want to create a modal popup in my webpage, but I don't know enough about them to make one on my own. Can you help me with any links to tutorials, code, etc.?

This is what I want my modal to look like:

Answer: 
You might want to look into jQuery UI Dialogue <http://jqueryui.com/dialog/>

Names for that are: pop up, modal box, and dialogue box, though I'm sure there are plenty of others.
Check Twitter Bootstrap's Modals; they look something like that:

Stack overflow is not a place for you to get code. It is a place to post what you have already done and ask for help with revisions.
