下拉菜单 - Safar和Chrome中的问题，非常奇怪

Question

我有一个我正在研究的网站有一个问题，在Safari和Chrome上，下拉列表不会同时消失，并且文本在隐藏之前会暂停一瞬间。有没有人有这类问题的经验？

非常感谢任何可以帮助分享知识的CSS向导。

最好，安德鲁

            ul.menu,
            ul.menu li,
            ul.menu ul {
             list-style: none;
             margin: 0;
             padding: 0;
            }

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

            ul.menu li {
             float: left;
             line-height: 1.3em;
             vertical-align: middle;
             zoom: 1;




            }

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

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


            }


            ul.menu ul li {
             float: none;
            }

            ul.menu ul ul {
             top: 1px;
             left: 99%;
            }

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

Answer 1

这是因为你有一个转换集。您可以删除它，然后它将同步。

ul.menu, ul.menu li, ul.menu ul {
-webkit-transition: none;
-moz-transition: none;
-o-transition: none;
transition: none;
}
