Hi, here's what I'd like to be able to do...

On my homepage.
After a few seconds a message reveals itself.
It can slide in from top.
THIS I CAN DO: Animation Reveal. Brilliant.

Here's the trick
I'd ideally like a [X] box at the end of the line/element
So that once you have read it, you can make it go away.

Any ideas?
In Xara, there are animation to reveal but nothing to 'return/go-away/leave'?

Many thanks.
