I add the relevant white-space value inline.
nowrap
This value suppresses all line breaks in the element, except where it contains <br />s or <wbr />s.
This is the test paragraph with white-space: nowrap. It has all kinds of odd tabs and spacing in the HTML source code. Should they be preserved?
If the line of code stretches beyond the right border of the page, the browser should generate a horizontal scrollbar.
pre
This value makes the element behave as a <pre>: all line breaks, tabs and other oddities of the source code are literally followed.

pre-wrap
This value behaves as the pre value, except that it adds extra line breaks to prevent the text breaking out of the element's box.

Opera renders it like this:

pre-line
As far as I understand this value ignores tabs and multiple spaces, but it breaks off the text at hard returns in the source code, as well as when it's necessary to prevent the text from breaking out of its box.
