css中overflow属性是经常可以用到的属性，接下来的这篇文章我们就来看看css中overflow属性的具体用法。
我们首先来看一下overflow属性的值有哪些？
overflow 属性规定当内容溢出元素框时发生的事情。
overflow有以下四个属性值
visible：初始值，内容不会被修剪，会呈现在元素框之外。

scroll：内容会被修剪，但是浏览器会显示滚动条以便查看其余的内容。
hidden：内容会被修剪，并且其余内容是不可见的。
auto：如果内容被修剪，则浏览器会显示滚动条以便查看其余的内容。
下面我们来详细说一说overflow属性的这四个值
我们来看具体的示例
代码如下
HTML代码
CSS overflow The European languages are members of the same family. Their separate existence is a myth. For science, music, sport, etc, Europe uses the same vocabulary. The languages only differ in their grammar, their pronunciation and their most common words. Everyone realizes why a new common language would be desirable: one could refuse to pay expensive translators.

CSS代码
/*hidden*/div.hid{ width: 200px; height: 100px; overflow: hidden; background-color: #FF9999;}/*scroll*/div.scr{ width: 200px; height: 100px; overflow: scroll; background-color: #99FF99;}/*visible*/div.vis{ width: 200px; height: 100px; overflow: visible; background-color: #9999FF;}
在浏览器上显示如下结果
当overflow的属性值是hidden时，效果如下
在hidden的情况下，不会显示出剩下的部分，也不能滚动显示剩下的内容。
当overflow的属性值是scroll时，效果如下
在scroll的情况下，没有显示的内容可以滚动。默认的情况下，文字在横向上会折回，垂直方向显示滚动栏。
在css中设置white-space : nowrap（不自动改行的意思），也可以向横向滚动。
CSS代码
div.scr{ width: 200px; height: 100px; white-space:nowrap; overflow: scroll; background-color: #99FF99;}
效果如下
此外，也可以使用overflow-x和overflow-y属性对垂直和横向的滚动条的显示进行更为细致的设置。
当overflow的属性值是visible时，效果如下
visible的情况下，从盒子中溢出显示。紫色的部分是div盒子。默认的情况下，文字在div的横向width中被折回，并在纵向方向上显示。
这个也和scroll属性值一样，在css中设置white-space : nowrap，也可以横向滚动。
另外，如果不设置盒子的高度，就会自动改变盒子的高度。
div.vis{ width: 200px; /* height: 100px; */ overflow: visible; background-color: #9999FF;}
效果如下
最后，我们来看看当overflow属性值是auto时的具体情况
HTML代码

The languages only differ in their grammar, their pronunciation and their most common words. Everyone realizes why a new common language would be desirable: one could refuse to pay expensive translators.
CSS代码
div.aut{width: 200px;height: 100px;overflow: auto;background-color: red;}
在浏览器上运行的效果和scroll相似
