内容背后的wordpress网站菜单[关闭]

Question

我的 WordPress 网站上的菜单出现在多个页面的内容后面的问题。 iv 一直在网上寻找解决方案，并且 iv 查看了 z-index 并一直在使用不同的值来应用，但仍然没有运气。

如果有任何帮助，我将不胜感激

我的网站是：www.thehelpingworld.com

(p.s.请注意当屏幕宽度低于800px时会出现可折叠菜单)

提前谢谢你

Answer 1

在#main-navigation > .sf-menu > ul类中添加一个正数z-index，将使下拉菜单出现在页面内容的前面。

#main-navigation > .sf-menu > ul {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    max-height: 0;
    max-width: 16em;
    overflow: hidden;
    background: #333;
}

会变成

#main-navigation > .sf-menu > ul {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    max-height: 0;
    max-width: 16em;
    overflow: hidden;
    background: #333;
    z-index: 999;
}
