html - Add :hover to decendent -


मैं निम्न में एक होवर कैसे जोड़ूं: 

  table.pvtTable tr th, table.pvtTable tr th   
 मैं इसे अंतिम "वें" तत्व में जोड़ना चाहता हूं।  
 अगर मैं करता हूं:  
  तालिका    
   
 
 div class = "post-text" itemprop = "text"> 
 यह अंतिम  th  के लिए काम करेगा:  
  table.pvtTable tr th: last- बच्चे   
 और : होवर  चयनकर्ता के साथ समान तत्व:  
  table.pvtTable tr th: आखिरी बच्चा: होवर < / कोड>
