我有一个看起来像对话框的
。主要的
是对话框,而:before则代表箭头。我想做的是当你在CSS中将鼠标悬停在
上时,也会更改:before。
这是我的代码:
.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;
}
