在导航和下拉之间创建一个间隙

Question

有人知道我如何在导航和下拉菜单之间创建一个小间隙吗？我尝试过，但没有成功。

我的导航栏是这样的：

<div class="navigation">
<ul class="menu">
    <li><a href="#">Worker</a></li>
    <li><a href="#" class="sub">Categories</a>
        <ul>
            <li><a href="#">Webdesign</a></li>
            <li><a href="#">Inspiration</a></li>
            <li><a href="#">Tutorials</a></li>
            <li><a href="#">Development</a></li>
        </ul>
    </li>
    <li><a href="#">Shop</a></li>
    <li><a href="#">Account</a></li>
</ul>

我把我的代码粘贴到jsfiddle

如果有人有办法解决这个问题，我将不胜感激。

Answer 1

好吧，因为这里有点混乱，我决定打开一个新的答案，这里有一种方法：

.navigation {
    height: 50px;
    overflow: visible;
}
.navigation li {
    height:  60px;
}

基本上，你可以通过设置第一级li格栅的高度来将其向下推，该格栅比容器的高度（10px）更高。

Answer 2

body > div > ul > li > ul {
border-top: 10px solid white;
}

这是如果你想让它悬停。

Answer 3

使用此：

.menu li:hover ul {margin-top: 10px;}

用于处理保证金非悬停问题：

.menu li:hover ul {padding-top: 10px;}

可以试试这个吗？

.menu li:hover ul li:first-child {margin-top: 10px;}

Answer 4

我建议在您的html <div class="sepLine"></div>中使用div和以下css：

.sepLine{
    height: 15px;
    position: relative;
    width: 100%;
    top: 50px;
}

同时从该类中删除行高度并添加高度：

.menu a
    {  
        font: 500 15px Open Sans;
        display: block; 
        color: white; 
        height: 50px; /*Change line-height with height*/
        color: #FFF;
        width: 140px;
        text-align: center;
        display: inline-block;
    }

最后添加行高度：

.menu > li > ul > li > a{
        line-height: 50px; /*Add line height*/
    }
