View Full Version : Blue buttons should turn red when mouse over

Hi,

I coded a web page with two set of maps. Left and right map has their own blue/red buttons which should turn from blue to red when the mouse is over them. The left set of buttons stay blue even mouse over. What's the problem? The play function(animate) doesn't work either. Why?
