    background: #fff;
    border-bottom-right-radius: 5px;
    border-bottom-left-radius: 5px;
    visibility: hidden;
    opacity: 0;
    min-width: 100%;
    position: absolute;
    margin-top: 5px;

    display: none;
    padding-bottom: 10px;

.desktop-header ul li:hover > ul,
.desktop-header ul li:focus-within > ul,
.desktop-header ul li ul:hover,
.desktop-header ul li ul:focus {
    visibility: visible;
    opacity: 1;
    display: block;
}

Answer 1

这似乎是 focus-within 选择器的问题。如果您将 CSS 更改为以下内容，它会起作用：

.desktop-header ul li:hover > ul,
.desktop-header ul li:focus > ul,
.desktop-header ul li ul:hover,
.desktop-header ul li ul:focus {
    visibility: visible;
    opacity: 1;
    display: block;
}
