Instead of using alert, I would use Pop Up. And I recommend you use something like jQuery Dialog, see http://jqueryui.com/demos/dialog/

You cannot do this through alert() .

You can simulate it using a modal dialog. There are many modal dialog libraries - jQuery UI is quite powerful.

If you are asking how to display HTML markup as such in a warning window, do it:

 alert("\<html\>\<body\>\<h1\>this is alert heading\</h1\>\</html\>\</body\>")

If you ask how to format the warning window using HTML, you cannot. You need to create a modal dialog box, as one of the other answers shows.
