I tried to use MagicLine jQuery Navigation on my website, but I've run into a small problem. 
I want the underline to be precisely as long as the word that it's currently highlighting. Instead it's a few pixels longer and I simply can't deal with that. I tried to fix it with CSS but I failed. I believe the solution of this problem can be found in jQuery code, but I'm not familiar with it so I'm asking you for help. **How to shorten the length of the underline in jQuery?**
