Stylish popup in javascript?

javascript, jquery

Solution

This is not possible with traditional browse popups. You have to use a javascript/modal popup.

Here's an example:

http://jqueryui.com/dialog/#modal-confirmation

Problem

The alert box/confirm box which we get in javascript are simple popup box. I need to modify the box style. Means to make the text bold, and to make these pop up stylish. How can I achieve that??
