CSS solves the problem that letters without spaces are too long and numbers do not wrap automatically.

The Code is as follows. Note the Style:

<Div class = "detail_title" style = "word-break: break-all;"> <% = StringUtil. toHTML (title) %> </div>

By default, text of a DIV or other elements is not automatically wrapped if there is no text separator or space. For example:

<Div class = "detail_title" style = "word-break: break-all;"> too many bytes </div>

In this form, if you have encountered problems before, please refer to them if you need them.
Word-break: break-all;

Is forced to break the word.
