html - 防止自动换行 tag

Answer 1

The problem was caused by twitter bootstrap. For whatever reason, they added the following styles to the code tag:

white-space:pre;
white-space:pre-wrap;
word-break:break-all;
word-wrap:break-word;

By overwriting the styles with:

white-space: pre;
word-break: normal;
word-wrap: normal;

The problem was fixed.

Answer 2

I hope this might help you. Demo

.content pre
{
    white-space: -moz-pre-wrap;
    white-space: -pre-wrap;
    white-space: -o-pre-wrap;
    white-space: pre-wrap; 
    word-wrap: break-word; /* Internet Explorer 5.5+ */  
}
