Facebook Canvas Fluid Canvas

Has anyone built anything using the new "fluid canvas"?

Besides the sample code not working in IE 8, are there any other problems with doing this? I'm wondering if I would be nuts to build an 开发者_如何学Capplication using this? I mean, what would I do, check the available width of the screen and do different things for every user?

Isn't this prone to error? Any thoughts? Thanks!

even for "fluid" canvas, it is very likely that we are not going to check the available width of the screen (as the screen/browser window can be resize dynamically by the user).

instead, as it is an iframe, it is exactly the same way how we should built the canvas / web page that meet our needs or show best to the user by making use of the full width of the browser window.
