Değişiklik: ne zamandan önce: ana DIV?

Question

Konuşma balonuna benzeyen bir div var. Ana div kabarcık ve: önce ok. Yapmak istediğim şey, CSS'de :hover DIV'yi döndürdüğünüzde, :before'u da değiştirecektir.

.sidebar_image_box_newsfeed_user_info_comments { color: #ffffff; background-color: #2f2f2e; text-decoration: none; -webkit-transition-property: background-color, color, text-decoration; -webkit-transition-duration: 0.5s, 0.5s, 0.5s; } 

.sidebar_image_box_newsfeed_user_info_comments:hover { background-color: #3b3b3b; color: #f3f3f3; text-decoration: underline; } 

.sidebar_image_box_newsfeed_user_info_comments:before { content:""; position:absolute; bottom:-6px; right:0; border-width:0 0 6px 6px; border-style:solid; border-color:transparent #2f2f2e; text-decoration: none; -webkit-transition-property: background-color, color, text-decoration; -webkit-transition-duration: 0.5s, 0.5s, 0.5s; }
