Answer 1

这可能是因为你降低链接的文字大小。
更新：您减小字体大小在这里：

h5 a, #top_center li a {text-decoration: none; font-size: .75em; padding-top: 0px;} 

然后文本被对齐框的底部。 垂直居中它们，你可以这样做：

#top_center a { 
    vertical-align: middle; 
    } 

更新2： 好与你的整个CSS不能正确莫名其妙对齐。但是，这对我的作品：

#top_center a { 
    display: table-cell; 
    vertical-align: middle; 
    } 

参考：vertical-align
