javascript - Pause section and scroll inside a div -

i'm working on client site , i'm having issue firguring out how make work. goal pause @ section , continue scroll inside iphone continue scroll once iphone has finished scrolling. have attempted use position fixed on section body continues scroll i'm not sure if right solution. wondering if skrollr assist well. have ideas?

i've added fiddle of layout: https://jsfiddle.net/9lm6he4j/1/

psuedo html:

<section>     <div class="iphone_wrap">         <div class="iphone_inner">             <!--message content-->         </div>     </div> </section> 

css:

section {    position:relative;    min-height:500px;    width:100%; }  .iphone_wrap {     width:400px;     height:650px;     position:absolute;     left:20%;     top:-200px;     background:url('iphone.jpg'); }  .iphone_inner {     position:relative;     margin:0 auto;     overflow:scroll; } 

one way can

• use javascript/jquery , set position fixed of "blue color section" , "iphone wrapper"

  content run inside phone implement part of underlying body of page

  so blue section + iphone wrapper work overlay while content of iphone scroll below section

  and using js/jquery can reset position fixed relative after end of content.
