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;

你可以使用这个CSS

p {
  width: min-content;
  min-width: 100%;
}

一个服务器端解决方案，对我来说是:$message = wordwrap($message, 50， "<br>"， true);其中$message是一个字符串变量，包含要拆分的单词/字符。50是任何给定段的最大长度，“<br>”是你想要每(50)个字符插入的文本。

试试这个CSS属性-

overflow-wrap: anywhere;

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;
}

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;
