滚动到特定div时隐藏div

Question

I have a slideshow that has a height set to auto so any height image can be displayed. Within that slideshow I have two arrows which are wrapped in a div with a class of .center. The arrows are at a fixed position so when scrolling the arrows would follow. The function that is assigned to div="center" will display when you scroll over the div .center.

The problem I am having is once I scroll past the slide show div the arrows are still present. But when I scroll up past my slide show div the arrows are hidden.

How can I set up my script for when I scroll down to div 2 or end of slide show which has a class of cs-slider the center will be hidden?

 $(window).scroll(function() {
    $(".center").each( function() {
      if( $(window).scrollTop() > $(this).offset().top - 150 ) {
        $(this).css('opacity',1);
      } else {
        $(this).css('opacity',0);
      }
    }); 
 });

HTML

 <section class="cs-slider" style="margin-bottom: 80px;" >
  <div class="center" id="box" >
      <a href=# id="prev">Prev</a> 
      <a href=# id="next">Next</a>
  </div>
     <div class="slides cycle-slideshow"
        data-cycle-fx="fade"
        data-cycle-prev="#prev"
        data-cycle-next="#next"
       data-cycle-pager=".pager"
        data-cycle-loader="wait"
        data-cycle-swipe=true
        data-cycle-swipe-fx=scrollHorz
        data-cycle-auto-height=container
        data-cycle-center-horz=true
       data-cycle-timeout="0"
        data-cycle-speed="500"
>
<div class="pager"></div>
  </div>
  </section><!-- slider -->
  <section class="workContent fadeDown"><!-- Hide .center once you scroll over section -->

  </section>

CSS

 cs-slider .slides  { margin:0 auto; max-width:800px; display:block; z-index:1}
 .cs-slider             { position:relative; text-align:center; padding:4em 0em 1em 0em;}
 .center                    {opacity: 0; }
 #prev, #next               { position:fixed; top: 0%; width: 10%; height: 200px; cursor: pointer; text-indent:-9999px;}
