 according to the following steps (highest to lowest priority):If any META 
 declarations specify the "Content-Style-Type", the last one in the character stream 
 determines the default style sheet language. Otherwise, if any HTTP headers specify 
 the "Content-Style-Type", the last one in the character stream determines the 
 default style sheet language. Otherwise, the default style sheet language is 
 "text/css".
