我正在处理标题菜单，并且其中一个菜单项具有与之关联的下拉菜单。下拉菜单的背景应为透明，项目列表应为灰色背景色。但是，当我将背景的不透明度更改为0时，所有子元素<li>都继承了不透明度，而且我似乎无法使<li>具有任何背景色。
我曾尝试研究顶级的透明属性，也曾尝试过'background：transparent;'。整个下拉菜单上的“属性”，然后是background-color的{{1}}属性。
<li>我希望下拉菜单的背景是透明的，菜单selector ul.sub-menu.elementor-nav-menu--dropdown.sm-nowrap {
opacity: 0;
}
selector li.menu-item.menu-item-type-post_type.menu-item-object-our_work.menu-item-126 {
margin-top: 10px;
}
selector li.menu-item.menu-item-type-post_type.menu-item-object-
our_work {
margin-top: 10px;
background-color: rgba(0, 0, 0, .6)
}
的{{1}}是浅灰色。
