Uhmm, now I understand. But, It's stranger, I have to use same named class design in two spans and one table, I can't make it, cos that two span and table is diferent layout. The table contein some HTML button panel, and span has two label colls and those must be fadeOut when new form fadeIn over table and spans.
Well, forget it, The true way like you sayed "You will need to go back to your original design and change it so that you use different ID's and/or have some named class". cos I need create one class just only for fades, and class should be only for layouts not for elements coletions. Thank all and you a lot.
