水平导航使当前li更高

Question

我正在研究水平导航，其中列表项需要跨越整个宽度并且“活动”列表项需要高于其余项。

通过将 ul 设置为 display: table 和 list items to display: table-cell 成功地使列表项跨越整个宽度。

#l-primary-nav ul {
    width: 100%;
    margin: 0;
    padding: 0;
    overflow: hidden;
    display: table;
}

#l-primary-nav li {
    display: table-cell;
    text-align: center;
    line-height: 40px;
}

我不知道如何使“活动”列表项比其他项高一点。以为我会为 #l-primary-nav li（上）设置一个 margin-top: 5px 并从活动 li（下）中删除 margin-top，但是表格单元格项目不接受边距。

#l-primary-nav li.active {
    background: #fff;
    border-left: 1px solid #c2c2c2;
    border-right: 1px solid #c2c2c2;
}

到目前为止，这里是导航栏的链接：FIDDLE

我希望“关于”导航项比其他导航项高约 5 个像素。希望使用仅 CSS 的解决方案。任何见解将不胜感激。

谢谢！

Answer 1

这可能对你有帮助

 #l-primary-nav li {
     display:block;
     width:140px;
     float:left;
     text-align: center;
     margin-top:4px;
     border: 1px solid #c2c2c2;
 }

我已经为 li 元素提供了 display:block 并添加了宽度：

请参考以下fiddler：Here

HTML

<div id="l-primary-nav">
<ul class="l-inline">
    <li><a href="#">Home</a>
    </li>
    <li class="active"><a href="#">About</a>
    </li>
    <li><a href="#">Articles</a>
    </li>
    <li><a href="#">Calendar</a>
    </li>
</ul>

CSS

l-primary-nav {
width: 600px;
margin: 0 auto; 
}
.l-inline li {
display: inline-block;
}
l-primary-nav ul {
width: 99.8%;
margin: 0;
padding: 0;
border: 1px solid #c2c2c2;

}
l-primary-nav li a{
line-height: 40px;

border-right: 1px solid #c2c2c2;
border-top: 1px solid #c2c2c2;
}

Answer 3

根据上述建议的解决方案，我能够保持列表项跨越整个宽度，同时为活动列表项提供更高的高度。代码链接：http://jsfiddle.net/melcsweeney/xc5Y2/

#l-primary-nav {
width: 600px;
margin: 0 auto;
}
.l-inline li {
display: inline-block;
}
#l-primary-nav ul {
width: 99.8%;
margin: 0;
padding: 0;
border-left: 1px solid #c2c2c2;
border-right: 1px solid #c2c2c2;
border-bottom: 1px solid #c2c2c2;
float: left;
display: table;
}
#l-primary-nav li {
text-align: center;
display: table-cell;
vertical-align: bottom;
border-top: 1px solid #c2c2c2;
}

#l-primary-nav li a{
line-height: 40px;
height: 41px;
border-top: 1px transparent;
display: block;
background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0.18, #FBFBFB), color-stop(1, #D1D1D1));
