我们起首来看一下overflow属性的值有哪些？
overflow 属性规定当内容溢出元素框时发作的事变。
overflow有以下四个属性值
visible：初始值，内容不会被修剪，会呈如今元素框以外。
scroll：内容会被修剪，然则浏览器会显现转动条以便检察其他的内容。
hidden：内容会被修剪，而且其他内容是不可见的。
auto：假如内容被修剪，则浏览器会显现转动条以便检察其他的内容。
下面我们来仔细说一说overflow属性的这四个值
我们来看仔细的示例
代码以下
HTML代码
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>CSS overflow</title>
<link rel="stylesheet" type="text/css" href="sample.css">
</head>
<body>
<div class="hid">
<p>
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.
</p>
</div>
<br>
<div class="scr">

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;
}
在浏览器上显现以下结果
当overflow的属性值是hidden时，结果以下
在hidden的情况下，不会显现出剩下的部份，也不能转动显现剩下的内容。
当overflow的属性值是scroll时，结果以下
在scroll的情况下，没有显现的内容能够转动。默许的情况下，笔墨在横向上会折回，垂直方向显现转动栏。
在css中设置white-space : nowrap（不自动转业的意义），也能够向横向转动。
CSS代码
div.scr{
width: 200px;
height: 100px;
white-space:nowrap;
overflow: scroll;
background-color: #99FF99;
}
结果以下
别的，也能够运用overflow-x和overflow-y属性对垂直和横向的转动条的显现举行更加仔细的设置。
当overflow的属性值是visible时，结果以下
visible的情况下，从盒子中溢出显现。紫色的部份是div盒子。默许的情况下，笔墨在div的横向width中被折回，并在纵向方向上显现。
这个也和scroll属性值一样，在css中设置white-space : nowrap，也能够横向转动。
别的，假如不设置盒子的高度，就会自动转变盒子的高度。
div.vis{
width: 200px;
/* height: 100px; */
overflow: visible;
background-color: #9999FF;
}
结果以下
末了，我们来看看当overflow属性值是auto时的仔细情况
HTML代码
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>CSS overflow</title>
<link rel="stylesheet" type="text/css" href="sample.css">
</head>
<body>
<div class="aut">
<p>
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.
</p>
</div>
</body>
</html>
CSS代码
div.aut{
width: 200px;
height: 100px;
overflow: auto;
background-color: red;
}
在浏览器上运转的结果和scroll类似
