Hi,

I am building new top page for my website shiaconnect.com

This is the old frame shiaconnect dot com/index.php

and

This is the new frame shiaconnect dot com/indexnew.php

Now in indexnew.php i want to make menu active as menu hover i mean i want to display hover as active background for menu so when i visit (shiaconnect dot com/indexnew.php it shows menu hover as active menu means show white background as active for menu.

How do i do this ?

Please post code or attach zip with changes.

Also facebook.png is using transparent png so is it possible i can show white background like it shows in menu hover ?

Thankyou.
