Really cool effects can be applied very simply using page objects coloured the same as background image side panels, background colours and for recent browsers, table cell colours.

To see the five button colours on similar backgrounds select a radio button then click on New Background. I have used slower server scripts to give viewers with older "Java Challenged" browsers an opportunity to get a few ideas too. DO NOT use the Reload Button.

Red Blue  Ochre Green Grey Normal

...and for browsers with Java Script Enabled, pick a New Background: Red Blue Ochre Green Grey Normal
