How to change the unityObject's width height?

I’m using

in a browser, however I found out changing the display style to none actually unloads the unityObject. I’ve read somewhere it’s possible to change the width height of the unityObject to a 1x1 pixel so it’s still running in the background while something else is displayed on the screen. Can anyone tell me how to do this or provide a link that sends me me in the right direction?

Anyone?
