这对我很有效

word-wrap: normal;
word-break: break-all;
white-space: normal;
display: block;
height: auto;
margin: 3px auto;
line-height: 1.4;
-webkit-line-clamp: 1;
-webkit-box-orient: vertical;

使用word-wrap:break-word属性以及所需的宽度。主要是, 宽度以像素为单位，而不是百分比。

width: 200px;
word-wrap: break-word;

在HTML正文中尝试:

<table>
    <tr>
        <td>
            <div style="word-wrap: break-word; width: 800px">
                Hello world, how are you? More text here to see if it wraps after a long while of writing and it does on Firefox but I have not tested it on Chrome yet. It also works wonders if you have a medium to long paragraph. Just avoid writing in the CSS file that the words have to break-all, that's a small tip.
            </div>
        </td>
    </tr>
</table>

在CSS正文尝试:

background-size: auto;

table-layout: fixed;

<p style="word-wrap: break-word; word-break: break-all;">

在引导3中，确保空白没有设置为“nowrap”。

div {
  width: 200px;
  word-break: break-all;
  white-space: normal;
}

div {
    /* Set a width for element */
    word-wrap: break-word
}

“换行”解决方案只适用于IE和支持CSS3的浏览器。

最好的跨浏览器解决方案是使用您的服务器端语言(php或其他)来定位长字符串，并定期在其中放置html实体​ 这个实体很好地分割了长单词，并且适用于所有浏览器。

e.g.

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa​aaaaaaaaaaaaaaaaaaaaaaaaaaaaa
