The whiteSpace property applies only to elements that have layout. An element has layout when it is absolutely positioned, is a block element, or is an inline element with a specified height or width. Notice the width specification above to make it an element with layout. The links themselves are straight-forward. You just change the whiteSpace property to the desired value. Notice the usage of void() above. It is necessary to avoid overwriting of the page with the return value from the javascript: call, which is the property assignment value (normal or nowrap).
