By hihain:

Just a few lines ahead you can find
.nav-tabs > li > a,
.nav-pills > li > a {
...
line-height: 14px; // keeps the overall height an even number
}

I think ist is useful to remove the line-height there and put it in a new selector:

.nav-pills > li > a {
line-height: 14px; // keeps the overall height an even number
}

What do you think?
