Question

如果您在“关于ISL”下查看here - ＆gt; “董事会”你可以看到我创建了第三级下拉菜单，但我怎样才能正确对齐下拉？下面你会看到我的CSS。

#menudiv {
    width: 999px;
    float: left;
    clear: left;
    height: 250px;
    background: url(images/top_bg.png) no-repeat;
    margin-top: 10px;
}
#mainmenu {
    width: 948px;
    height: 63px;
    float: left;
    margin-left: 16px;
    margin-top: 5px;
    border: 1px solid #D5D5D5;
    -moz-border-radius: 3px;
    -webkit-border-radius: 3px;
    -webkit-box-shadow: 0px 1px 2px rgba(0,0,0,0.1);
    -moz-box-shadow: 0px 1px 2px rgba(0,0,0,0.1);
    background: url(images/nav_bg.gif) repeat;
}
.mainnav {
    margin: 0;
    padding: 0;
    list-style: none;
}
.mainnav * {
    margin: 0;
    padding: 0;
    list-style: none;
}
.mainnav ul {
    position: absolute;
    top: -999em;
    display: none;
}
.mainnav li {
    float: left;
    position: relative;
    z-index: 999;
    height: 63px;

    border-bottom: solid 0px #ccc;
    background: white;

.mainnav ul li {
    width: 132px;

.mainnav li:hover ul,
ul.mainnav li.sfHover ul {
    left: 0px;

    padding-top: 0px;
    width: 132px;
    border-bottom: solid 0px #eaeaea;

    padding: 6px 0 0px 0px;

    -moz-border-radius-bottomleft: 3px;

    width: 175px;
    border-bottom-left-radius: 3px 3px;
    border-bottom-right-radius: 3px 3px;
}
.mainnav li:hover li ul,
.mainnav li.sfHover li ul {
    top: -999em;
}
.mainnav li li:hover ul,
ul.mainnav li li.sfHover ul {
    left: 132px;
    top: -8px;
}
.mainnav li:hover ul,
.mainnav li li:hover ul {
    top: -999em;
}
.mainnav li li {
    color: #555;
    display: block;
    padding: 0px;
    height: auto !important;
    border: none;
    width: 175px;
    background: url(images/nav_dropdown_bg.gif) repeat;
    margin: 0;
}
.mainnav li li a:link,
.mainnav li li a:visited {
    display: block;
    height: auto !important;
    line-height: 30px;
    color: #333;
    font-weight: normal;
    font-family: arial,helvetica,sans-serif;
    font-size: 12px;
    border: none;
    margin: 0;
    padding-left: 10px;
    overflow: hidden;
    border-bottom: 1px solid #E3E3E3;
}
.mainnav li li :hover {
}
.mainnav li li a:hover {
    background: none;
    color: #555 ;
    border-bottom: 1px solid #E3E3E3;
}

问题是ul.sub-menu li ul.sub-menu离左边太远并且被其父级覆盖。如何修复这些ul元素的正确对齐方式？

Answer 1

在line 211的{{1}}上，通过类似mainmenu.css的内容调整子菜单的left位置，这样可以将子菜单置于更舒适的位置。
