</ul>
</nav>
</section>

而 CSS 是

#action-bar .navbar {
    float: left;
}
#action-bar nav ul ul {
    display: none;
}
#action-bar nav ul li:hover > ul {
    display: block;
}
#action-bar nav ul {
    background: #fff;
    padding: 0;
    list-style: none;
    position: relative;
    display: inline-table;
    margin: 0;
    text-align: center;
    font-size: 15px;
    font-family:'Oswald', sans-serif;
    font-weight: bold;
}
#action-bar nav ul:after {
    content:"";
    clear: both;
    display: block;
}
#action-bar nav ul li {
    float: left;
}
#action-bar nav ul li:hover {
    background: #6f100d;
}
#action-bar nav ul li a {
    display: block;
    color: #757575;
    text-decoration: none;
    border-right: 1px solid #E5E5E6;
    border-bottom: 1px solid #E5E5E6;
    transition: .8s background-color;
}
#action-bar nav ul li a:hover {
    color: #fff;
}
#action-bar nav ul ul {
    background: #fff;
    padding: 0;
    position: absolute;
    top: 100%;
}
#action-bar nav ul ul li a {
    color: black;
}
#action-bar nav ul ul li {
    float: none;
    position: relative;
}
#action-bar nav ul ul li a {
    padding: 15px 40px;
    color: black;
}
#action-bar nav ul ul li a:hover {
    background: #6ABED6;
    color: #fff;
}
#action-bar nav ul ul ul {
    position: absolute;
    left: 100%;
    top:0;
}
#action-bar nav ul li:hover > a {
    color: #fff;
}
#action-bar #view-cart {
    float: right;
    display: inline-block;
    padding-top: 18px;
    padding-left: 5px;
}
#action-bar #user-menu {
    display: inline-block;
    padding-left: 160px;
}
.menu .menu-item {
    display: inline-block;
    margin: 0;
    padding: 0;
}
.main-menu .menu-item a {
    color: #fff;
    display: block;
    text-decoration: none;
    font-family:'Oswald:500', Arial, sans-serif;
    font-smoothing: antialiased;
    text-transform: uppercase;
    overflow: visible;
    background: #fff;
}
.three-d span, .three-d span::before, .three-d span::after {
    display: block;
    transition: all .3s ease-out;
    transform-style: preserve-3d;
}
.three-d {
    position: relative;
    cursor: pointer;
    transition: all .07s linear;
}
.three-d span {
    display: block;
    padding: 18px 35px;
    perspective: -200px;
}
.three-d span::before, .three-d span::after {
    padding: 18px 35px;
    content: attr(title);
    width: 100%;
    height: 100%;
    position: absolute;
    top: 0;
    left: 0;
    background: #fff;
    box-sizing: border-box;
}
.three-d span::before {
    transform: rotateX(0deg) translateZ(25px);
}
.three-d span::after {
    transform: rotateX(-90deg) translateZ(25px);
    background: #6f100d;
    color: #f9f9f9;
}
.three-d:hover span, .three-d:focus span {
    transform: translateZ(-25px) rotateX(90deg);
}

我希望主菜单在我悬停在子菜单上时保留悬停样式，使用 CSS，但我无法实现。

有人可以帮忙吗？

Answer 1

更改CSS的最后一个块...

.three-d:hover span, .three-d:focus span {
    transform: translateZ(-25px) rotateX(90deg);
}

对此...

li:hover .three-d span, .three-d:focus span {
    transform: translateZ(-25px) rotateX(90deg);
}

并将其余 a:hover { 选择器更改为 li:hover > a {
