Bootstrap JS Tab and CSS : get rid of the underline style

Question

I am using the bootstrap JS tab. Unfortunately, I deleted a few lines in my CSS file (and of course don't remember which one). Do you know how I could get rid of the underline style in my various tabs in order to restore a style similar to http://www.w3schools.com/bootstrap/tryit.asp?filename=trybs_ref_js_tab&stacked=h ?

Many thanks for your help.

Look at text-decoration.

.nav-tabs a {
  text-decoration: none;
}
