让pre标签自动换行示例代码

pre{
white-space:pre-wrap; /* css3.0 */
white-space:-moz-pre-wrap; /* Firefox */
white-space:-pre-wrap; /* Opera 4-6 */
white-space:-o-pre-wrap; /* Opera 7 */
word-wrap:break-word; /* Internet Explorer 5.5+ */
}

pre{white-space:pre-wrap; white-space:-moz-pre-wrap; white-space:-pre-wrap; white-space:-o-pre-wrap; word-wrap:break-word; /*我是一个很长很长的代码，看我换行了木有？*/}
