Below is the necessary CSS to ensure proper functionality, especially for accommodating very long texts that wrap around (multi-line link texts):
.tabs-bottom{
list-style: none;
margin: 0;
padding: 0;
}
.tabs-bottom li{
width: 216px;
height: 55px;
line-height: 50px;
background: #000;
display: inline-block;
text-align: center;
}
.tabs-bottom li a
{
line-height:16px; /*This prevents inheriting the li's line-height*/
display:inline-block;
vertical-align: middle;
}
To test it out, you can use this fiddle:

Please Note
Unfortunately, jsFiddle may not work in IE 7 and 8, so I couldn't verify its performance on those browsers.
