我的子菜单在悬停时消失了。请教我如何修复它。

#header {
    padding-left: 0;
    padding-right: 0;
    position: relative;
}
.wp-toolbar #header{
    margin-top: 0;
}
#site-title, #site-description {
    padding-left: 20px;
}

#theme-logo img {
    box-shadow: none;
}

/* =Navigation
*/
#top-navigation {
    position: absolute;
    bottom: -10px;
    right: 0;
}


#theme-top-menu {
    display:-moz-inline-stack;
    display:inline-block;
    zoom:1;
    *display:inline;
}
#theme-top-menu .sub-menu {
    left: auto;
    right: 0px;
}
.menu .current_page_item a, .menu .current-menu-item a {
    background-color: transparent;
}

#theme-top-menu a {
    padding: 0 0.9em;
    border: none;
    font-weight: normal;
    font-size: 80%;
}

#site-navigation{
    padding: 0;
    position: relative;
    max-width: 1140px;
    border-top: 1px solid #666666;
    -webkit-border-top-left-radius: 10px;
    -webkit-border-top-right-radius: 10px;
    -moz-border-radius-topleft: 10px;
    -moz-border-radius-topright: 10px;
    border-top-left-radius: 10px;
    border-top-right-radius: 10px;
}
.fullwidth #site-navigation {
    max-width: 100%;
}
#site-navigation .theme-wrap {
    padding: 0 5px;
    position: relative;
    min-height: 50px;

}
#theme-menu-main {
    margin: 0 auto;
    background-color: transparent;
}
#theme-menu-main > li {
    border: none;
    border-right: 1px solid rgba(255, 255, 255, 0.2);
    margin: 0;
    padding: 10px 0;
}
#theme-menu-main > li a {
    border: none;
    font-weight: bold;
}
#theme-menu-main > li:hover {
    background-color: transparent;
}
#theme-menu-main > li > ul {
    top: 50%;
    left: 0.9em;
    padding: 10px 0;
}
#theme-menu-main > li ul > li a {
    margin: 0 10px;
    padding: 5px 10px;
    border: none;
    border-bottom: 1px solid rgba(255, 255, 255, 0.2);
    font-weight: 100;
}
#theme-menu-main > li ul > li:last-child a{
    border: none;
}
#theme-menu-main > li > a span{
    padding: 0 0 2px;
    border-bottom: 3px solid transparent;
}

#theme-menu-main a {
    background-color: transparent;
    font-weight: 100;
}

.menu a:hover { background: none; }

最佳答案

尝试这个：

ul li:hover ul {
display:block;
}
