Simple question for the slide tab menu

[Ange52]

In the example given, there is a thin gray underline (given in the 7th line of CSS code) that, while it does help out the tabs effect, I'm not so much a fan of it. My only issue is that it continues on to the right too far. Does anyone out there have any tips on how I can cut it off a bit earlier? Or just limit the underline only to the width of the image tabs? All input here is welcome, of course.

Thanks,
Ange52
