Bootstrap button - remove outline on Chrome OS X

For any googlers like me, where..

.btn:focus {
    outline: none;
}

still didn't work in Google Chrome, the following should completely remove any button glow.

.btn:focus,.btn:active:focus,.btn.active:focus,
.btn.focus,.btn:active.focus,.btn.active.focus {
    outline: none;
}

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;
}
