Labels let the contents of the label output as is

When the data is inserted into the library by <textarea>, it becomes a line when it is taken, and the <pre> tag can be used as the input format.

It's time to add some CSS styles to <pre>.

The following is the referenced content:

<style>
Pre {
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+ */
Word-break:break-all;
Overflow:hidden;
}
</style>

The CSS scheme allows the text in the pre tag to wrap, and I've tested it on all my browsers, all supported, Ie6,ie7, IE8, Firefox, Opera, Safari and Chrome.

The boundary is exceeded only if you narrow the window to a width less than 20 characters.
