Nope. How the alert window is rendered is entirely up to the browser.

You would have to use a JavaScript based dialog windows alternative like jQuery UI Dialog.

No, this is controlled by the browser. I don't use alerts anymore I use jQuery UI dialog, it's fully customizable

As far as I know, it is not possible.

However, you have a several choices:

If you want to create it yourself as a totally custom thing, create a new div element in your DOM (as the last child of the body, and give it the maximum z-index you can or you use), position that absolute (top:0,left:0), and write there HTML whatever you want. With some JS you can positon it to center of the screen/layout. :)

Or use jQuery UI Dialog... :)
