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;

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+ */
}

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

</p>

你可以使用这个CSS

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

试试这个:

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

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。
