Question

我想在此CSS中添加平滑动画过渡到下拉列表。哪个代码和我应该放在哪里？我尝试了一些“webkit-transition”变体，但没有一个与我的编程技巧一起工作。任何人都可以解决这个问题吗？

  ul.jb_free_dropdown,
    ul.jb_free_dropdown li,
    ul.jb_free_dropdown ul {
      list-style: none;
      margin: 0;
      padding: 0;
      font-family: Arial, Helvetica, sans-serif;
    }

    ul.jb_free_dropdown {
      position: relative;
      z-index: 597;
      float: left;
    }

    ul.jb_free_dropdown li {
      float: left;
      min-height: 1px;
      line-height: 1.3em;
      vertical-align: middle;

    }

    ul.jb_free_dropdown li.hover,
    ul.jb_free_dropdown li:hover {
      position: relative;
      z-index: 599;
      cursor: default;
    }

    ul.jb_free_dropdown ul {
      visibility: hidden;
      position: absolute;
      top: 100%;
      left: 0;
      z-index: 598;
      width: 100%;

    }

    ul.jb_free_dropdown ul li {
      float: none;

    }

    ul.jb_free_dropdown ul ul {
      top: 0px;
      left: 100%;                
    }

    ul.jb_free_dropdown li:hover > ul {
      visibility: visible;
    }


    /* -- Base drop-down styling -- */

    ul.jb_free_dropdown {
      font-weight: bold;
    }

        ul.jb_free_dropdown li {

通常情况下，转换效果会伴随父css选择器，以及＆＃34;你想要结束的结果＆＃34;将在:hover选择器上。

我过去曾经使用过它，它可以在各种浏览器中使用：

CSS

.view .mask {
   -webkit-transform: translatex(0) translatey(100px);
   -moz-transform: translatex(0) translatey(100px);
   -o-transform: translatex(0) translatey(100px);
   -ms-transform: translatex(0) translatey(100px);
    transform: translatex(0) translatey(100px);
   -webkit-transition: all .8s ease-out;
   -moz-transition: all .8s ease-out;
   -o-transition: all .8s ease-out;
   -ms-transition: all .8s ease-out;
    transition: all .8s ease-out;
    }

.view:hover .mask {
   -webkit-transform: translatey(0);
   -moz-transform: translatey(0);
   -o-transform: translatey(0);
   -ms-transform: translatey(0);
    transform: translatey(0);
    }

添加到CSS的转换
