当我将光标悬停在我自己的wordpress主题中的下拉菜单(单击“M”徽标)时,我已经成功添加了过渡效果,但是当光标离开下拉菜单时没有显示过渡关闭时的效果。您可以查看我自己的主题on this link以获取更多信息。
此处下拉css样式:
.dropdown-menu {
border-bottom-right-radius: 77px;
border-bottom-left-radius: 77px;
/* background: url(img/submenu.png) no-repeat scroll right/ 91% 100%; */
position: absolute;
height:0;
top: 100%;
left: 0;
z-index: 1000;
display: none;
float: left;
min-width: 153px;
padding: 1px 0;
margin: 2px 0 0 0;
list-style: none;
font-size: 14px;
text-align: center;
background-color: transparent!important;
border: 1px solid #ccc;
border: 1px solid rgba(0,0,0,0.15);
background-clip: padding-box;
opacity: 0;
top: 35px;
visibility: hidden;
-webkit-transition:height 300ms ease-in;
-moz-transition:height 300ms ease-in;
-ms-transition: height 300ms ease-in;
-o-transition:height 300ms ease-in;
transition:height 300ms ease-in;
overflow: hidden;
}
.navbar-nav li:hover .dropdown-menu {
opacity: 1;
top: 105px;
visibility: visible;
height:300px;
}
那么如何在下拉菜单关闭时添加过渡效果?
答案 0 :(得分:0)
而不是只转换高度,你可以尝试
-webkit-transition: all 300ms ease-in;
-moz-transition: all 300ms ease-in;
-ms-transition: all 300ms ease-in;
-o-transition: all 300ms ease-in;
transition: all 300ms ease-in;
