我想要我的 megamenu div comeout 有一些过渡效果所以我添加 visibility: hidden; opacity: 0; on .submenu class and visibility: visible;不透明度:1; 在 ul.menu1 li:hover .submenu class 上。它正在工作但是当我将鼠标悬停在一个菜单到另一个菜单时它会自动显示以前的菜单代码就像我将鼠标悬停在联系我们菜单上然后悬停在产品菜单上然后鼠标向下移动任何链接然后它会转到联系菜单选项卡并显示联系人菜单代码。
如果我删除可见性和不透明度属性并添加简单的display:none;和display:block;那么它工作正常但我想要我的 megamenu 悬停并带有一些淡淡的效果。
我想要这个网站 ( https://www.margcompusoft.com/ ) 大型菜单悬停效果样式。
我附上 html 和 css 代码供您引用。
