小編給大家分享一下CSS中overflow屬性如何使用，希望大家閱讀完這篇文章后大所收獲，下面讓我們一起去探討吧！
CSS中overflow屬性是經(jīng)常可以用到的屬性，接下來的這篇文章我們就來看看CSS中overflow屬性的具體用法。
我們首先來看一下overflow屬性的值有哪些？
overflow 屬性規(guī)定當(dāng)內(nèi)容溢出元素框時發(fā)生的事情。
overflow有以下四個屬性值
visible：初始值，內(nèi)容不會被修剪，會呈現(xiàn)在元素框之外。
scroll：內(nèi)容會被修剪，但是瀏覽器會顯示滾動條以便查看其余的內(nèi)容。
hidden：內(nèi)容會被修剪，并且其余內(nèi)容是不可見的。
auto：如果內(nèi)容被修剪，則瀏覽器會顯示滾動條以便查看其余的內(nèi)容。
下面我們來詳細(xì)說一說overflow屬性的這四個值
我們來看具體的示例
代碼如下
HTML代碼
<!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">

</div>
</body>
</html>CSS代碼
/*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;
}在瀏覽器上顯示如下結(jié)果
當(dāng)overflow的屬性值是hidden時，效果如下
在hidden的情況下，不會顯示出剩下的部分，也不能滾動顯示剩下的內(nèi)容。
當(dāng)overflow的屬性值是scroll時，效果如下
在scroll的情況下，沒有顯示的內(nèi)容可以滾動。默認(rèn)的情況下，文字在橫向上會折回，垂直方向顯示滾動欄。
在css中設(shè)置white-space : nowrap（不自動改行的意思），也可以向橫向滾動。
CSS代碼
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屬性對垂直和橫向的滾動條的顯示進(jìn)行更為細(xì)致的設(shè)置。
當(dāng)overflow的屬性值是visible時，效果如下
visible的情況下，從盒子中溢出顯示。紫色的部分是div盒子。默認(rèn)的情況下，文字在div的橫向width中被折回，并在縱向方向上顯示。
這個也和scroll屬性值一樣，在css中設(shè)置white-space : nowrap，也可以橫向滾動。
另外，如果不設(shè)置盒子的高度，就會自動改變盒子的高度。
div.vis{
width: 200px;
/* height: 100px; */
overflow: visible;
background-color: #9999FF;
}效果如下
最后，我們來看看當(dāng)overflow屬性值是auto時的具體情況
HTML代碼
<!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代碼
div.aut{
width: 200px;
height: 100px;
overflow: auto;
background-color: red;
}在瀏覽器上運(yùn)行的效果和scroll相似
