Jquery doubt

[php75]

Can anyone explain this code?.i cant understand this code....

 

jQuery(window).scroll(function(){
        var vscroll=jQuery(this).scrollTop();
        jQuery('#text').css(
        {
           "transform" :"translate(0px,"+vscroll/2+"px)"
        });

1. .scroll(function) will "bind an event handler to the 'scroll' Javascript event".

2. .scrollTop() will "get the current vertical position of the scroll bar".

3. .css(object) will "set one or more CSS properties".

 

All together,

When the window scrolls, get the current scroll position of the window as "vscroll", then set the #text element's "transform" CSS attribute to be translate(0px,vscroll/2 as px).

If you're not sure what that means, see it in action.
