我想创建一个Css下拉菜单，我已经完成了下拉部分，但是我似乎无法模拟转换，也不知道如何编写这些转换。以下是我到目前为止的情况，感谢您的帮助。

body {
 font-family: 'Lucida Grande', 'Helvetica Neue', Helvetica, Arial, sans-serif;
padding: 20px 50px 150px;
font-size: 13px;
text-align: center;
background: #E3CAA1;

}

ul {
text-align: left;
    display: inline;
    margin: 0;
    padding: 15px 4px 17px 0;
    list-style: none;
    -webkit-box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
    -moz-box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
    box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
    }
    ul li {
    font: bold 12px/18px sans-serif;
    display: inline-block;
    margin-right: -4px;
    position: relative;
    padding: 15px 20px;
    background: #fff;
    cursor: pointer;
    -webkit-transition: all 0.2s;
    -moz-transition: all 0.2s;
    -ms-transition: all 0.2s;
    -o-transition: all 0.2s;
    transition: all 0.2s;
  }
    ul li:hover {
    background: #555;
    color: #fff;
  }
    ul li ul {
    padding: 0;
    position: absolute;
    top: 48px;
    left: 0;
    width: 150px;
    -webkit-box-shadow: none;
    -moz-box-shadow: none;
    box-shadow: none;
  display: none;
  opacity: 0;
  visibility: hidden;
  -webkit-transiton: opacity 0.2s;
  -moz-transition: opacity 0.2s;
  -ms-transition: opacity 0.2s;
  -o-transition: opacity 0.2s;
  -transition: opacity 0.2s;
}
ul li ul li { 
  background: #555; 
  display: block; 
  color: #fff;
  text-shadow: 0 -1px 0 #000;
}
ul li ul li:hover { background: #666; }
