Question

我希望菜单的下拉部分有两个边框，然后抛出菜单的下拉部分。我还想摆脱下拉菜单右侧显示的蓝色边框。

下图显示了我遇到的问题以及我想要的问题：

以下是导航菜单的代码：

<div style="text-align: left;">

要摆脱小蓝三角，请删除此规则：

#mbt-menu ul li:first-child > a:after {
    content: '';
    position: absolute;
    left: 40px;
    top: -6px;
    border-left: 6px solid transparent;
    border-right: 6px solid transparent;
    border-bottom: 6px solid #469ee8;
}

要删除下拉菜单中的背景框，请添加以下规则：

#mbt-menu ul {
    border: none !important;
    padding: 0 !important;
}

要删除框右侧的蓝色边框（实际上是框阴影），请删除以下规则：

#mbt-menu li {
    float: left;
    border-right: 1px solid #328ad4;
    -moz-box-shadow: 1px 0 0 #469ee8; /* DELETE */
    -webkit-box-shadow: 1px 0 0 #469ee8; /* DELETE */
    box-shadow: 1px 0 0 #469ee8; /* DELETE */
    position: relative;

要调整下拉菜单的位置，以便与父链接很好地对齐，请在此处调整left和top属性：

#mbt-menu ul {
    margin: 20px 0 0 0;
    _margin: 0;
    opaciaty: 0;
    visibility: hidden;
    position: absolute;
    top: 46px; /* ADJUST DROP DOWN */
    left: 0;  /* ADJUST DROP DOWN */
    z-index: 9999;
    background: #ffffff;
    -moz-border-radius: 3px;
    -webkit-border-radius: 3px;
    border-radius: 3px;
    -webkit-transition: all .2s ease-in-out;
    -moz-transition: all .2s ease-in-out;
    -ms-transition: all .2s ease-in-out;
    -o-transition: all .2s ease-in-out;
    transition: all .2s ease-in-out;
}

Answer 2

你基本上想要这样的东西：

#mbt-menu ul {border:none; padding: 0;}

#mbt-menu li li {box-shadow: none; border-width: 2px 2px 0 2px;}

#mbt-menu li li:last-child {border-bottom-width: 2px;}

但是，我不会像这样添加样式。这仅用于演示目的。您可能需要使这些样式更具体，以覆盖已有的样式。（我刚刚通过CSS终端测试过。）理想情况下，将这些样式集成到它们所属的现有代码中。

您有影响子ul / li的父级ul / li的样式，因此理想情况下将这些规则更改为仅使用顶级级别的规则，使用子选择器（>）。
