Changing color of required fields on wrong entry

[gubbachchi]

Hi,

I have a application where there are number of fields for name, age etc designed with PHP ans CSS. There are some required fields with * marking, when the user forgets to enter the data or makes any wrong entry, the field color should change. How to achieve this is CSS.
Please anybody give me some hints regarding this.

With regards

Neither html or css can do this. You must ask on the PHP board.

Javascript should be able to do this pretty easily. This thread may help: http://bytes.com/forum/thread638199.html
