CSS Issue with menu bar

I see how that might be it but I can see how to turn that off.  I tried this but nothing.

.btn:not(.disabled):not(:active):focus {
  outline: 0px auto #074373;
  outline-offset: -2px;
}

You can just turn it off for all invisible buttons on focus, like:

.btn.btn-invisible.dropdown-toggle:focus {
  outline: none;
}
