If the user has their browser set 600X800, then they will just be able to see the Flash content and not the trees. However, if they widen their browser to lets say 800X800, then they will be able to see the trees. As they further widen their browser, the website will automatically slide the trees across the page so that the trees do not stack up on top of each other, stack on top of the content, and are not clipped off on the edges of the browser. In addition, I am wondering if for every 100 pixels or so if a tree can also be placed in as well?
I am also wondering how I would get the clouds to float from right to left. I remember there was a HTML tag <marquee>. Would this be the best option for me, or is there an alternative?
