just one div scrollable on page

Question

I need nothing on page to be scrollable except one div (divleft), and it should be scrollable by mouse, not by scrollbar. All scrollbars should be hidden.

I treid a solution with narrower parent div (divleftwrap), but id doesnt work.

<div id="slidetop">
323<br>
323<br>
323<br>
</div>
<div id="menutop"></div>
<div id="wrapt">
<div id="divleftwrap">
<div id="divleft">
...
</div>
</div>
<div id="divright">
...
</div>
<div class="clear"></div>
</div>

css

html, body{
  overflow:hidden;
}
#slidetop{
    display:none;
}
#menutop{
    height:25px;
    background:red;
}
#divleftwrap{
    float:left;
    width:60%;
    background:blue;
    height:100%;
}
#divleft{
    width:clac(100% + 17px);
    background:green;
  overflow-y:scroll;
}
#divright{
    width:25%;
  float:right;
    background:lightblue;
}

js - this should stay to work

$("#menutop").click(function(){
    $("#slidetop").slideToggle();
});

HERE IS JSFIDDLE

Answer 1

I changed a bit your style sheet due a little error. In order to verify the scroll I reduced the height.

In the following the snippet:

$("#menutop").click(function(){
  $("#slidetop").slideToggle();
});

html, body{
  overflow:hidden;
}
#slidetop{
  display:none;
}
#menutop{
  height:25px;
  background:red;
}
#divleftwrap{
  float:left;
  width:60%;
  background:blue;
  height:200px;
  overflow: hidden;
}
#divleft{
  width:calc(100% + 17px);
  height: 110%;
  background:green;
  overflow-y:scroll;
}
#divright{
  width:25%;
  float:right;
  background:lightblue;
}
