When applying CSS to <button> element, there seems to a "fixed" padding between the button element and the content in the button. This occurs even if there the padding is set to 0 for the button element.

Reproducible: Always

There are "gaps" as shown by "black" between the two borders (gray and white). All elements have padding and margin set to 0.

The only possible hack to make it work is: 

button::-moz-focus-inner {
  border:0;
  padding:0;
}
