Remove Focus Border on Chrome

[orwells-ghost]

I just wanted to give a heads up. In Chrome, after pressing the hamburger, a focus border shows up. See image.

To fix:
.hamburger:focus { outline: 0; }

In my case this helped me:

.hamburger:focus {
-webkit-tap-highlight-color: rgba(0,0,0,0);
}

You can also do:

.hamburger:focus {
  outline: none;
}

Removing the outline is a bad practice in terms of accessibility.
