work with HTML use div and iframe(vista effect)

    recently , because of work requirement, write UI work Like after clicking yahoo turn off button's popup message(or vista).

    after study I know use div and iframe can make it work.

    write a div with the highest zIndex and iframe's zIndex higher then div . Give a filter like (filter:alpha(opacity=xx)) to div . then you will get it.

    but this method have problem with IE6 work together with select box. ok, write a iframe with lower zIndex then div and filter with oopacity=0 to make it transparent.

    this is just a work note. experience exchange is welcomed.
