Hi,
I have requested full milestone, since it is a small amount. You can release it after the work is done. So no worries there.
Regarding the work. I'm assuming you are aiming for fixed size width the way you already have in flash only that it would be javascript.
I would need a div in that area and the banner will be inside that.
I would use html5 canvas to perform the same(using javascript), no plugins, but some js library files would have to be included in your html. Will that be alright? It works on all devices and browsers that support html5.
Secondly you have a mouse over transition in first header banner, on touch devices it will happen during tap instead (because mouse position cannot be tracked without touching the screen) Ofcourse if the user touches the screen and moves the finger we might be able to use the mousemove functionality the way you have it already but that may even result in inbuilt touch functions over-riding where the browser itself may move. Like the user scrolling the entire window.
Let me know and I'll get it done for you.
Thanks very much.
