According to which rules specified in CSS will that be the case?  Given 
that CSS (assuming you meant to use class selectors instead), all three 
markup samples will be blue.  The order of the class names in the markup 
is irrelevant.  The order of the rules specified in the CSS is relevant 
and the latter rule of equal specificity takes precedence.
