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;

试试这个:

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

我用过自举法。 我的html代码看起来像..

<div class="container mt-3" style="width: 100%;">
  <div class="row">
    <div class="col-sm-12 wrap-text">
      <h6>
        text content
      </h6>
    </div>
  </div>
</div>

CSS

.wrap-text {
     text-align:justify;
}

你可以像这样使用软连字符:

啊

这将显示为

aaaaaaaaaaaaaaa-
aaaaaaaaaaaaaaa

如果装盒不够大，或者

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

如果是的话。

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。

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;
