css – Click through div to underlying elements

css – Click through div to underlying elements

Yes, you CAN do this.

Using pointer-events: none along with CSS conditional statements for IE11 (does not work in IE10 or below), you can get a cross browser compatible solution for this problem.

Using AlphaImageLoader, you can even put transparent .PNG/.GIFs in the overlay div and have clicks flow through to elements underneath.

CSS:

pointer-events: none;
background: url(your_transparent.png);

IE11 conditional:

filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src=your_transparent.png, sizingMethod=scale);
background: none !important;

Here is a basic example page with all the code.

Yes, you CAN force overlapping layers to pass through (ignore) click events.
PLUS you CAN have specific children excluded from this behavior…

You can do this, using pointer-events

pointer-events influences the reaction to click-, tap-, scroll- und hover events.


In a layer that should ignore / pass-through mentioned events you set

pointer-events: none; 

Children of that unresponsive layer that need to react mouse / tap events again need:

pointer-events: auto; 

That second part is very helpful if you work with multiple overlapping div layers (probably some parents being transparent), where you need to be able to click on child elements and only that child elements.

Example usage:

.parent {
  pointer-events:none;        
}
.child {
  pointer-events:auto;
}
<div class=parent>
  <a href=#>Im unresponsive</a>
  <a href=# class=child>Im clickable again, wohoo !</a>
</div>

css – Click through div to underlying elements

Allowing the user to click through a div to the underlying element depends on the browser. All modern browsers, including Firefox, Chrome, Safari, and Opera, understand pointer-events:none.

For IE, it depends on the background. If the background is transparent, clickthrough works without you needing to do anything. On the other hand, for something like background:white; opacity:0; filter:Alpha(opacity=0);, IE needs manual event forwarding.
