Transitions effects with text

[Vamsee Krishna]

Hi all,
Can I use transition effects like fade in etc. with my text???
i've designed some pages and in the index page, i got a table and some forms...each table data is a link and on mouse over, one of the forms becomes visible which describes the link...now, i want some transition effect when the form becomes visible and invisible rather than just appearing and disappearing...if I don't seem to make any sense, pls check out
this site (http://196.12.44.6/~vamsee_k/oly).

Can you help me out?
thanking u all in anticipation
