.css一长串没有空格的字符，让其在容器边界内换行，通过 word-break: break-all;实现如下，如果不这样的话，Author response:就会和后面的内容分别处于不同的行:

<div class="large-8 response-edit-content" style="word-break: break-all;">
    <strong>User response:</strong> {{ historyItem.submissionHistoryComments.comment }}
</div>

渲染之后的结果:
User response: sdddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd

下面这个是不需要的:
User response: 
sdddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd
