假设你有一些样式和标记:
ul
{
white-space: nowrap;
overflow-x: visible;
overflow-y: hidden;
/* added width so it would work in the snippet */
width: 100px;
}
li
{
display: inline-block;
}
<div>
<ul>
<li>1</li> <li>2</li> <li>3</li>
<li>4</li> <li>5</li> <li>6</li>
<li>7</li> <li>8</li> <li>9</li>
<li>1</li> <li>2</li> <li>3</li>
<li>4</li> <li>5</li> <li>6</li>
<li>7</li> <li>8</li> <li>9</li>
<li>1</li> <li>2</li> <li>3</li>
<li>4</li> <li>5</li> <li>6</li>
<li>7</li> <li>8</li> <li>9</li>
</ul>
</div>
当你看到这个。<ul>在底部有一个滚动条，尽管我已经为溢出x/y指定了可见和隐藏值。
(Chrome 11和opera (?))
我猜一定有一些w3c规范或什么东西告诉这发生了，但对于我的生活，我不明白为什么。

更新:-我找到了一种方法，通过添加另一个元素包裹在ul实现相同的结果。来看看。
我在尝试构建一个固定定位的边栏时就遇到过这个问题，边栏边界外显示的边栏包含垂直可滚动的内容和嵌套的绝对定位子栏。
我的方法包括分别应用:
侧栏元素的overflow: visible属性
一个overflow-y: auto属性到侧边栏内部包装器
请查看下面的示例或在线代码库。
html {
min-height: 100%;
}
body {
min-height: 100%;
background: linear-gradient(to bottom, white, DarkGray 80%);
margin: 0;
padding: 0;
}
.sidebar {
position: fixed;
top: 0;
right: 0;
height: 100%;
width: 200px;
overflow: visible; /* Just apply overflow-x */
background-color: DarkOrange;
}
.sidebarWrapper {
padding: 10px;
overflow-y: auto; /* Just apply overflow-y */
height: 100%;
width: 100%;
}
.element {
position: absolute;
top: 0;
right: 100%;
background-color: CornflowerBlue;
padding: 10px;
width: 200px;
}

我最初发现了一个CSS方式绕过这个时，使用循环jQuery插件。Cycle使用JavaScript将我的幻灯片设置为overflow: hidden，所以当我将图片设置为width: 100%时，图片看起来会垂直切割，所以我强迫它们可见!important，为了避免显示幻灯片动画，我设置了overflow: hidden到幻灯片的容器div。希望这对你有用。
更新-新的解决方案:
原来的问题-> http://jsfiddle.net/xMddf/1/
(即使我使用overflow-y: visible，它也变成了“auto”和“scroll”。)
#content {
height: 100px;
width: 200px;
overflow-x: hidden;
overflow-y: visible;
}
新的解决方案-> http://jsfiddle.net/xMddf/2/
(我发现了一种变通方法，使用包装器div对不同的DOM元素应用overflow-x和overflow-y，就像James Khoury在将可见和隐藏结合到单个DOM元素的问题上所建议的那样。)
#wrapper {
height: 100px;
overflow-y: visible;
}
#content {
width: 200px;
overflow-x: hidden;
}
经过一番认真的搜索，我似乎找到了我问题的答案:
来自:http://www.brunildo.org/test/Overflowxy2.html
在Gecko, Safari, Opera中，“可见”
与连用时也变成auto
' hidden '(换句话说就是' visible ')
和组合时变成auto
还有什么不同的吗
“可见的”)。Gecko 1.8, Safari 3, Opera
9.5是相当一致的。
W3C规范还说:
' overflow-x '的计算值
' overflow-y '和their是一样的
指定的值，除了一些
与“visible”的组合则不是
可能:如果指定为
' visible '另一个是' scroll '或者
auto，然后visible设为
“汽车”。的计算值
' overflow '等于computed
如果' overflow-y '则' overflow-x '的值
是一样的;否则就是对
' overflow-x '的计算值
“overflow-y”。
短版:
如果你对overflow-x或overflow-y使用了visible，而对另一个使用了非visible，则可见值将被解释为auto。
