我想将文本包装在特定宽度的 div 内的两行内。如果文本超出两行的长度，那么我想显示省略号。 有没有办法使用 CSS 来做到这一点？
例如
Sample text showing wrapping
of text in only two line...
如果您设置元素的
line-heightheightoverflow:hidden;#someDiv {
line-height: 1.5em;
height: 3em; /* height is 2x line-height, so two lines will display */
overflow: hidden; /* prevents extra lines from being visible */
}
或者，您可以使用 CSS
text-overflowwhite-space#someDiv {
line-height: 1.5em;
height: 3em;
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;
width: 100%;
}
还有演示：
同时实现多行文本和省略号似乎是 javascript 的领域。
另一个简单快速的解决方案
.giveMeEllipsis {
overflow: hidden;
text-overflow: ellipsis;
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: N; /* number of lines to show */
line-height: X; /* fallback */
max-height: X*N; /* fallback */
}
原问答的参考是这里
仅限CSS
overflow: hidden;
display: -webkit-box;
-webkit-line-clamp: 2;
-webkit-box-orient: vertical;
我见过的最好的一个纯 CSS 且响应式的来自 Mobify 开发者博客 - CSS Ellipsis: How to Manage Multi-Line Ellipsis in Pure CSS:
CSS：
html, body, p { margin: 0; padding: 0; font-family: sans-serif;}
.ellipsis {
overflow: hidden;
height: 200px;
line-height: 25px;
margin: 20px;
border: 5px solid #AAA; }
.ellipsis:before {
content:"";
float: left;
width: 5px; height: 200px; }
.ellipsis > *:first-child {
float: right;
width: 100%;
margin-left: -5px; }
.ellipsis:after {
content: "\02026";
box-sizing: content-box;
-webkit-box-sizing: content-box;
-moz-box-sizing: content-box;
float: right; position: relative;
top: -25px; left: 100%;
width: 3em; margin-left: -3em;
padding-right: 5px;
text-align: right;
background: -webkit-gradient(linear, left top, right top,
from(rgba(255, 255, 255, 0)), to(white), color-stop(50%, white));
background: -moz-linear-gradient(to right, rgba(255, 255, 255, 0), white 50%, white);
background: -o-linear-gradient(to right, rgba(255, 255, 255, 0), white 50%, white);
background: -ms-linear-gradient(to right, rgba(255, 255, 255, 0), white 50%, white);
background: linear-gradient(to right, rgba(255, 255, 255, 0), white 50%, white); }
HTML：
<div class="ellipsis">
<div class="blah">
<p>Call me Ishmael. Some years ago – never mind how long precisely – having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world. It is a way I have of driving off the spleen, and regulating the circulation. Whenever I find myself growing grim about the mouth; whenever it is a damp, drizzly November in my soul; whenever I find myself involuntarily pausing before coffin warehouses, and bringing up the rear of every funeral I meet; and especially whenever my hypos get such an upper hand of me, that it requires a strong moral principle to prevent me from deliberately stepping into the street, and methodically knocking people's hats off – then, I account it high time to get to sea as soon as I can.</p>
</div>
</div>
我相信纯CSS解决方案
text-overflow: ellipsis.yourdiv {
line-height: 1.5em; /* Sets line height to 1.5 times text size */
height: 3em; /* Sets the div height to 2x line-height (3 times text size) */
width: 100%; /* Use whatever width you want */
white-space: normal; /* Wrap lines of text */
overflow: hidden; /* Hide text that goes beyond the boundaries of the div */
text-overflow: ellipsis; /* Ellipses (cross-browser) */
-o-text-overflow: ellipsis; /* Ellipses (cross-browser) */
}
您尝试过 http://tpgblog.com/thirddots/ 的 jQuery 吗？
Webkit 的 CSS 唯一解决方案
// Only for DEMO
$(function() {
$('#toggleWidth').on('click', function(e) {
$('.multiLineLabel').toggleClass('maxWidth');
});
}).multiLineLabel {
display: inline-block;
box-sizing: border-box;
white-space: pre-line;
word-wrap: break-word;
}
.multiLineLabel .textMaxLine {
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: 2;
line-clamp: 2;
overflow: hidden;
}
/* Only for DEMO */
.multiLineLabel.maxWidth {
width: 100px;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="multiLineLabel">
<span class="textMaxLine">This text is going to wrap automatically in 2 lines in case the width of the element is not sufficiently wide.</span>
</div>
<br/>
<button id="toggleWidth">Toggle Width</button>尝试这样的事情：http://jsfiddle.net/6jdj3pcL/1/
<p>Here is a paragraph with a lot of text ...</p>
p {
line-height: 1.5em;
height: 3em;
overflow: hidden;
width: 300px;
}
p::before {
content: '...';
float: right;
margin-top: 1.5em;
}
通常单行截断非常简单
.truncate-text {
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}
两行截断有点棘手，但可以使用 css 来完成，这个例子是在 sass 中。
@mixin multiLineEllipsis($lineHeight: 1.2rem, $lineCount: 2, $bgColor: white, $padding-right: 0.3125rem, $width: 1rem, $ellipsis-right: 0) {
overflow: hidden; /* hide text if it is more than $lineCount lines */
position: relative; /* for set '...' in absolute position */
line-height: $lineHeight; /* use this value to count block height */
max-height: $lineHeight * $lineCount; /* max-height = line-height * lines max number */
padding-right: $padding-right; /* place for '...' */
white-space: normal; /* overwrite any white-space styles */
word-break: break-all; /* will break each letter in word */
text-overflow: ellipsis; /* show ellipsis if text is broken */
&::before {
content: '...'; /* create the '...'' points in the end */
position: absolute;
right: $ellipsis-right;
bottom: 0;
}
&::after {
content: ''; /* hide '...'' if we have text, which is less than or equal to max lines and add $bgColor */
position: absolute;
right: 0;
width: $width;
height: 1rem * $lineCount;
margin-top: 0.2rem;
background: $bgColor; /* because we are cutting off the diff we need to add the color back. */
}
}
参见 http://jsfiddle.net/SWcCt/。
只需设置
line-heightheightline-height:20px;
height:40px;
当然，为了使
text-overflow: ellipsisoverflow:hidden;
white-space: pre;
<tag> {
max-height: calc(2 * 1.5em); /* 2 lines of 1.5em each */
line-height: 1.5em;
overflow: hidden;
text-overflow: ellipsis;
display: -webkit-box;
-webkit-line-clamp: 2; /* number of lines to show */
-webkit-box-orient: vertical;
}
此代码使用 -webkit-box 和 -webkit-line-clamp 属性来实现仅显示 2 行文本，然后为任何剩余文本添加省略号的所需效果。 max-height 属性将 p 元素的最大高度设置为 3em（每行 1.5em 的 2 行），而 line-height 将每行的高度设置为 1.5em。溢出属性设置为隐藏以隐藏超出最大高度的任何溢出，并且text-overflow设置为省略号以为任何隐藏文本添加省略号。
@Asiddeen bn Muhammad 的解决方案对我有用，只需对 css 进行一些修改
.text {
line-height: 1.5;
height: 6em;
white-space: normal;
overflow: hidden;
text-overflow: ellipsis;
display: block;
-webkit-line-clamp: 2;
-webkit-box-orient: vertical;
}
我对此有答案“实现多行文本和省略号似乎是 Javascript 的领域”。
WebkitLineClamp：https://developer.mozilla.org/en-US/docs/Web/CSS/-webkit-line-clamp WebKItBoxOrient：https://developer.mozilla.org/en-US/docs/Web/CSS/box-orient
`.textWithTwoLine {
overflow: hidden;
text-overflow: ellipsis;
display: -webkit-box;
-webkit-line-clamp: 2;
-webkit-box-orient: vertical;
}`
以下对我有用：
CSS：
.longWordBreakParent {
display: flex;
}
.longWordBreak {
word-break: break-all;
}
HTML：
<div className="longWordBreakParent">
<span className='longWordBreak'>someverylongtextthatcannotbefitinoneline</span>
</div>

在所有这些示例中，假设我们有：
#someDiv {
width: 250px;
overflow: hidden;
}
