我有一个水平列表，我在li标签上放置了边框以便将它们分开。它一切运作良好，但我在李的顶部有一些神秘的填充，这使得边框比文字更高：

我玩过填充和边距，但我无法弄清楚是什么导致了这一点。有什么建议吗？
这是html：
<div id="top_center">
<ul>
<li><a href="#">(1 New)</a></li>
<li><a href="#">Verified Account</a></li>
<li><a href="#">Prefrences</a></li>
</ul>
</div>

可能会减少链接的文本大小。
更新：您在此处减小字体大小：
h5 a, #top_center li a {text-decoration: none; font-size: .75em; padding-top: 0px;}
然后文本对齐到框的底部。 要将它们垂直居中，您可以这样做：
#top_center a {
vertical-align: middle;
}
更新2： 好吧你的整个CSS它不能以某种方式正确对齐。但这对我有用：
#top_center a {
display: table-cell;
vertical-align: middle;
}
