The value of white-space in css: pre-wrap

In CSS, how does one set the white-space attribute.
The default value "normal" indicates that blank spaces are ignored by the browser.

The white-space attribute declares how to process the blank characters in the elements during the layout process. Values pre-wrap and pre-line are newly added in CSS 2.1. Valid in IE8 or later, Firefox, and Chrome.

Pre-wrap indicates that the blank character sequence is retained, but the line feed is normal.
