How to implement animation-fade a div using opacity?

Why using opacity?

Now implemented using fadein with jQuery.
The problem is that the fadein animation is doing the "inserting" element in the middle of the content. As I need to until an element does not appear, underneath was an empty space for him

The animation when navidena, scroll, click, or within the scope of what you need?
Ideally, when doscroll so that the whole div was inside the client side browser, then the div vizuete - Joel.Schad commented on March 19th 20 at 09:34
@Joel.Schad, as I understand it until the unit is out of the videmo it opacity: 0. As soon as it becomes wideman it opacity: 1. Then create a function which defines a finding whether a block Zoni videmo

come function(elem) { var docViewTop = $(window).scrollTop(), docViewBottom = docViewTop + $(window).height(), elemTop = $(elem).offset().top, elemBottom = elemTop + $(elem).height(); return ((elemBottom <= docViewBottom) && (elemTop >= docViewTop)); }

if (come("#of ideaseconomy")) {
("#ideaseconomy"). addClass("visible") ;

Css will be like this
#of idialogpage{
Opacity: 0;
Opacity: 1;
