  16     The expression body[class="value"] is a CSS attribute selector where "body" is the html element to be styled, "class" the body's attribute to be
  17     manipulated, and "value" the class attribute's value, which is either portrait, landscapeLeft, or landscapeRight.
  18     This expression is used to dynamically select a body style according to the class attribute value. For instance, if the body's class attribute is set
  19     to landscapeLeft, then all style declarations matching body[class="landscapeLeft"] will be used to style "Handling iPhone or iPod touch Orientation Events". 
  20     The JavaScript updateOrientation function in the iPhoneOrientation.js file is used to set the body's class attribute to one of these values.

The secret to positioning the columns, is to use left and right margins to push the element (column being adjusted), away from it's siblings. In the above example the contents (outer box) is pushed away from the left (#contents { margin-left: 10.5em;}), and the articles (inner box) within the contents is pushed from the right (#wrapper #articles { margin-right: 18.5em; }).
