Currently, I am attempting to implement a dynamic <li> view limit within the content of a div. My goal is to display only 3 <li> elements each time the div content is scrolled.
Although not confirmed, I believe this example may be helpful:

Is this what you're looking for? http://jsfiddle.net/bennwbpu/1/
$(function(){
var liheight = $(".demo2 li").outerHeight();
$(".demo2").outerHeight(liheight*3);
})
We first determine the outer height of a single <li> and then we set the outer height of .demo2 to three times that value.
If you want the scroll position to snap to the top of the closest <li> whenever there is a scroll event, you can check out:

This solution may seem lengthy, but it was crafted through a combination of research and experimentation.
Streamlined approach
$(function(){
var lih = $(".demo2 li").outerHeight(),
lst = 0,
f=0;
$(".demo2").outerHeight(lih*3).scroll(function(e){
var $this = $(this),
st = $this.scrollTop();
function _scroll(n) {
$this.css("overflow","hidden").stop().animate({scrollTop:lst+(n)*lih*3}, 500, "swing", function(){setTimeout(
function(){
$this.css("overflow","auto");
setTimeout(function(){f=0},50);
},500)
})
}
if (!f) {
f=1;
if (st > lst)
_scroll(1);
else
_scroll(-1);
}
lst = st;
});
})
