问题
I am having a tough time with overflow: hidden.
Basically, I am trying to hide the overflow of an unordered list which is located in a <div>.
I have no idea why this isn't working though.
Instead of hiding it, it breaks my list from a horizontal layout to a vertical layout.
The unordered list is carousel and the container is list.
Below is my CSS code;
div.body .container .images {
background: url(/images/images-background.jpg);
height: 62px;
margin-bottom: 17px;
width: 384px;
}
div.body .container .images #images-previous {
cursor: pointer;
float: left;
}
div.body .container .images #images-next {
cursor: pointer;
float: left;
}
div.body .container .images .list {
float: left;
overflow: hidden;
vertical-align: top;
width: 336px;
}
div.body .container .images .carousel {
margin-bottom: 6px;
margin-top: 8px;
width: 336px;
}
Here, my HTML;
<div class="images">
<div id="images-previous">
<img src="/images/images-previous.jpg" width="24" height="62" alt="Previous" />
</div>
<div class="list">
<ul class="carousel">
<li>

回答1:
Ok if anyone else is having this problem this may be your answer:
If you are trying to hide absolute positioned elements make sure the container of those absolute positioned elements is relatively positioned.
回答2:
Actually...
To hide an absolute positioned element, the container position must be anything except for static. It can be relative or fixed in addition to absolute.
回答3:
In addition to provided answers:
it seems like parent element (the one with overflow:hidden) must not be display:inline. Changing to display:inline-block worked for me.
.outer {
position: relative;
border: 1px dotted black;
padding: 5px;
overflow: hidden;
}
.inner {
position: absolute;
left: 50%;
margin-left: -20px;
top: 70%;
width: 40px;
height: 80px;
background: yellow;
}<span class="outer">
Some text
<span class="inner"></span>
</span>
<span class="outer" style="display:inline-block;">
Some text
<span class="inner"></span>
</span>回答4:
Evidently, sometimes, the display properties of parent of the element containing the matter that shouldn't over should also be set to overflow:hidden as well, e.g.:
<div style="overflow: hidden">
<div style="overflow: hidden">some text that should not overflow<div>
</div>
Why? I have no idea but it worked for me. See https://medium.com/@crrollyson/overflow-hidden-not-working-check-the-child-element-c33ac0c4f565 (ignore the sniping at stackoverflow!)
