Bootstrap button – remove outline on Chrome OS X

I see .btn:focus has an outline on it:

.btn:focus {
  outline: thin dotted;
  outline: 5px auto -webkit-focus-ring-color;
  outline-offset: -2px;
}

Try changing this to:

.btn:focus {
  outline: none !important;
}

Basically, look for any instances of outline on :focused elements — that’s what’s causing it.

Update – For Bootstrap v4:

.btn:focus {
  box-shadow: none;
}
