I have a requirement to have an overlay div positioned (z-order) above a [pre] element that is scrollable. The problem is, I can no longer scroll within the pre element because the overlay is blocking it.
Q: Is there any way to pass scroll events through divs so that they reach underlying elements?
CSS:
.dropzone {
pointer-events:none;
}
#myimage {
float: left;
border-width: 0px;
border-style: none;
background-color:none;
padding: 0px;
position: relative;
}
#myoverlay {
position: absolute;
background-color:#139C8A;
background-image: url('../images/drag-icon-white.png');
background-size: 160px 66px;
background-repeat: no-repeat;
background-position: center;
opacity:0.0;
z-index:-1;
}
#myresponse {
float: right;
border-width: 0px;
border-style: none;
background-color:none;
padding: 0px;
position: relative;
}
.mycode {
text-align:left;
color:#EFEFEF;
background-color:#3C3C48;
border-width: 0px;
border-style: none;
overflow-y: scroll;
position: relative;
}
HTML:
<div class="container">
<div id="myoverlay"> </div>
<div class="row">
<div class="col-md-12">
<div id="myimage">
<canvas id="myCanvas" width="970" height="485"></canvas>
</div> <!-- end col-md-4 -->
<div id="myresponse">
<pre id="mycode" class="mycode">
<span style="color:#139C8A"><i>(Response will appear here)</i></span>
</pre>
</div>
<div id="dropzone" class="dropzone-detect detect-droppable"></div>
</div>
</div><!-- end row -->
</div> <!-- /container -->
You've assigned the CSS to the class .dropzone
. But there is no dropzone-class, just an ID! Try the following CSS:
#dropzone { pointer-events:none; }
But please note, that this isn't working in IE below version 11 . For those browser, you can use a polyfill .
