Allow specific tag to override overflow:hidden

Question

I've got a <div>, that's a certain height and width, and overflow:hidden so that specfic inner images are clipped; however I want one image in the <div> to pop out of the border (ie to override the overflow:hidden), how do I do this?

Answer 1

Z-index doesnt seem to work, but here I have a workaround which worked fine for me, as I needed overflow only to be "visible" when hovering a child element:

#parent {
   overflow: hidden;
}

#parent:hover {
   overflow: visible;
}

I know this is an old post, but this can be done (at least in Chrome). I figured this out about two years ago and it's saved me a couple times.

Set the child to have position of fixed and use margins instead of top and left to position it.

#wrapper {
    width: 5px;
    height: 5px;
    border: 1px solid #000;
    overflow: hidden;
}

#parent {
    position: relative;
}

button {
    position: fixed;
    margin: 10px 0px 0px 30px;
}

There is currently no way I am aware of to make a parent node with overflow hidden have children visible outside it (with the exception of position:fixed children).

HOWEVER, it is possible to instead of using overflow, you can just use the outline property set to the color of the background combined with the z-index property to mask some elements while retaining others like so.

.persuado-overflow-hidden {
 /*gives the appearance of overflow:hidden*/
  z-index: -100;
  position: relative;
  outline: 1000vw solid white;
  overflow: visible;
}
.overridevisible {
/*takes the element out of the persuado overflow hidden*/
  z-index: 1;
}
/*does the other styling to the text*/
.loremcontainer {
  width: 60vw;
  height: 60vh;
  margin: 20vw;
  border: 1px solid;
}
.loremtxt {
  width: 100vw;
  height: 100vh;
  margin: -20vh;
  z-index: -1;
}
.positionmessage {
  z-index: 100;
  position: absolute;
  top: -12vh;
  left: -5vw;
  right: -5vw;
  color: red;
}

<div class="persuado-overflow-hidden loremcontainer">
<div class="loremtxt">
<div class="overridevisible positionmessage">Then, theres this text outside the paragraphs inside the persuado overflow:hidden element</div>

All the above is nice but nothing beats JAVASCRIPT. (Using jquery). So,

<script>
var element = $('#myID');
var pos = element.offset();
var height = element.height(); // optional
element.appendTo($('body')); // optional
element.css({
    position : 'fixed'
}).offset(pos).height(height);
</script>

What I do is, get the original position of the element (relative to the page), optionally get the height or width, optionally append the element to the body, apply the new css rule position : fixed and finally apply the original position and optionally width and height.

The trick is to keep the overflow:hidden element with position:static and position the overflowing element relative to a higher parent (rather than the overflow:hidden parent). Like so:

.relative-wrap {
    /*relative on second parent*/
    position: relative;
}

.overflow-wrap {
    height: 250px;
    width: 250px;
    overflow: hidden;
    background: lightblue;
    
    /*no relative on immediate parent*/
}

.respect-overflow {
    position: relative;
    top: 75px;
    left: 225px;
    height: 50px;
    width: 50px;
    background: green;    
}
.no-overflow {
    position: absolute;
    top: 150px;
    left: 225px;
    height: 50px;
    width: 50px;
    background: red;
}

<div class="relative-wrap">
    
    <div class="overflow-wrap">
        
        <div class="respect-overflow">
        
        </div>
        <div class="no-overflow">
            
        </div>
        
    </div>
    
</div>

I also want to note, a very common use case for the desire to have an element overflow its container in this way is when you want animate the height of a dropdown or container from X to 0, and therefore need to have overflow: hidden on the container. Usually you have something inside the container that you want to overflow regardless. Since these elements are only accessibly when the container is "open", you can take advantage and set the overflow back to visible after the container is fully open, and then set it back to hidden before trying to animate the container back to height: 0.

You can overflow an element out of the div by wrapping it in another div, then set your image as position:absolute; and offset it using margins.

<div class="no-overflow">
<div>
<img class="escape" src="wherever.jpg" />
</div>
</div>

.no-overflow{
overflow:hidden;
width: 500px
height: 100px
}

.escape{
position: absolute;
margin-bottom: -150px;
}
