"the main soul of moveover
is in its CSS not in js ....
js is only an option in movover
u may have moveover with or without js"

What the difference of moveover from

non overlay is like the
default friendster.. when u add css or js
we call it enhanced non overlay or enhanced css

overlay uses pure html..
this is a very useful tricks once u master..
since the knowledge u will gain in overlaying
is applicable in website making.

xover is base more on js
to function...to mimic overlay looks

while our moveover may works
with or without js..to attain the overlay looks...
