是否有自动换行或其他属性阻止文本自动换行?我有一个高度，溢出:隐藏，文字仍然中断。
需要在CSS3之前的所有浏览器中工作。
div { white-space: nowrap; overflow: hidden; } <div>testing quite a lot of text that just doesn't wrap because it is too long a run-on sentance with so many useless words for you to not read today despite every effort you make to do so including stretching your browser width to the maximum length unless however you utilized your browser's zooming out feature or manually modifying the CSS in which case you are definitely cheating and ruining this fun little game of me typing out as many words as can be fitted into one ridiculously long run-on sentence of the twenty-first century anno domini using my traditional keyboard and two monitors at 1080p while going through every effort to painstakingly ramble on and on but just not exactly repeating myself short of reusing a couple of words in multiple places throughout this HTML even though that would be about a thousand times easier than what I'm currently doing on this day to pointlessly avoid work regardless of its futility given that it'll only create consequences for myself in having to work harder to catch up later of course all of that notwithstanding moderation efforts to tone back my extensive efforts to make this somewhat enjoyable to read while making it as long as possible who may or may not revert this edit in spite of its usefulness since the previous edit only contained four words that could not possibly wrap even without the CSS changes due to their short nature which is invariably going to create more questions than it answers such as can be found in the comments section which is exactly why I created this effort in order to address one of those about the purpose of the overflow attribute which if you have modified you will now see lets you read the entirety of this text through the benefits of horizontal scrolling features but on the other hand if only overflow was used and text-wrap was left out then you will continue to see a vertical scrollbar unless you set a fixed height for this div in which case you certainly should see that vertical overflow is hidden though that would only happen if you did not put this example into fullscreen short of having your viewport set to a small enough height which can actually be further defined to a designated number of lines as opposed to one by using a height set to a multiple of the CSS property defined by line-height which could be a percentage of white-space and that would indeed hide the vertical overflow of this mountain of text which I'm really quite surprised that you managed to linger on here to read through its frivolous nature on the famed site known by programmers as Stack Overflow and for that I congratulate you for potentially wasting your time</div>
注意:这只适用于块元素。如果你需要这样做的表格单元格(例如)，你需要在表格单元格内放置一个div，因为表格单元格有display table-cell not block。
从CSS3开始，表单元格也支持这一点。
使用text-overflow:省略号将添加…最后。
div {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}
只是要非常清楚，这适用于段落和标题等。你只需要指定display: block。
例如:
<h5 style="display: block; text-overflow: ellipsis; white-space: nowrap; overflow: hidden">
This is a really long title, but it won't exceed the parent width
</h5>
(原谅内联样式)
