I'm trying to create a web page that I would like to be able to view on any size browser. Is there a script or some sort of trick that I can read the visitors browser size before displaying?

This can be done with JavaScript.

Back in the day I used to just design my sites to fit on 800x600, but now most people have at least a 1024x768 resolution. So that's one thing you can always go by.

That's great, thank you. I'm surprise that CSS doesn't have a [centre command] that reads the browser. Will give this a try.
