The text-overflow property specifies how overflowed content that is not displayed should be signaled to the user. It can be clipped, display an ellipsis (...), or display a custom string.
Both of the following properties are required for text-overflow:
- white-space: nowrap;
- overflow: hidden;
text-overflow属性可以控制一行文字超过框以后超过的部分的显示形式。
<!DOCTYPE html>
<html>
<head>
<style>
div.a {
white-space: nowrap;
width: 50px;
overflow: hidden;
text-overflow: clip;
border: 1px solid #000000;
}
div.b {
white-space: nowrap;
width: 50px;
overflow: hidden;
text-overflow: ellipsis;
border: 1px solid #000000;
}
div.c {
white-space: nowrap;
width: 50px;
overflow: hidden;
text-overflow: "----";
border: 1px solid #000000;
}
</style>
</head>
<body>
<h1>The text-overflow Property</h1>
<p>The following two divs contains a text that will not fit in the box.</p>
<h2>text-overflow: clip (default):</h2>
<div class="a">Hello world!</div>
<h2>text-overflow: ellipsis:</h2>
<div class="b">Hello world!</div>
<h2>text-overflow: "----" (user defined string):</h2>
<div class="c">Hello world!</div>
<p><strong>Note:</strong> The text-overflow: "<em>string</em>" only works in
Firefox.</p>
</body>
</html>效果如下:
而且
- white-space: nowrap;
- overflow: hidden;
而且除了text-overflow以外，这两个属性也必须同时写上。
