Blockquote em Hover no blog

Post meio atrasado hehe...

 Boa noite povo,como vão?

---Pulando essa parte---

No post de hoje,eu peguei um tutorial do blog Adolescente Nerd (Todos os créditos).É um blockquote hover,que quando passa o mouse,outra cor ''fecha'' a área.Ah,e pra quem não sabe,blockquote é aquela caixinha que vemos muito em blogs de tutoriais html,que fica com os códigos dentro...

Cole o código acima da tag  ]>
(É onde são colados a maioria dos códigos HTML)
