At this time the heart 1w+ a grass mud horse ran over ~~~~~~~~

Directly on the solution:

<div class= "main_comment" > "" "" "" "</div><div class=" Commentbar "> Reply box </div>

. main_comment{  width:100%;  Position:absolute;  Overflow-y: auto;  top:0;  bottom:0;  -webkit-overflow-scrolling:touch;   /* This sentence is to slide smoother */}.commentbar{  width:100%;  Position:absolute;  bottom:0;  left:0;  Background: #fff;  padding:5px;  z-index:99;}
