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;

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;

将此CSS添加到段落中。

width:420px; 
min-height:15px; 
height:auto!important; 
color:#666; 
padding: 1%; 
font-size: 14px; 
font-weight: normal;
word-wrap: break-word; 
text-align: left;

在IE、Firefox、chrome、safari和opera中，如果单词中没有空格(比如一个很长的URL)，唯一适用的方法是:

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

我发现这个是防弹的。

跨浏览器

.wrap
{
    white-space: pre-wrap; /* css-3 */    
    white-space: -moz-pre-wrap; /* Mozilla, since 1999 */
    white-space: -pre-wrap; /* Opera 4-6 */    
    white-space: -o-pre-wrap; /* Opera 7 */    
    word-wrap: break-word; /* Internet Explorer 5.5+ */
}

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;
}
