How to custmize & Design the `alert()` box?

Question

Here is script in my website's footer that will check that specific font installed or not in computer. If installed or not it will prompt alert box. I want to customize:

• Design of that alert box
• Replace the 'OK' button with 'Download' button that also have download link.
• Write some RTL words in new paragraph. For Example Urdu words like آپ کے کمپیوٹر میں۔۔۔۔

Just accept that it's not going to be an alert() box, but rather it's just going to be normal HTML+CSS. So you will just position the box wherever you want it with whatever buttons you want and whatever way you want it to look. Or if so you'd whish their are plugins which already do this for you (though they limit your options quite a bit of course). You might want to look at jQuery UI if you're using jquery for example (specifically the dialog component of jQuery UI).
