Something strange is happening with the styling of my button. There seems to be an outline around it that I can't explain. Can anyone help me understand why this is happening?
button {
padding: 1em;
background: transparent;
border: none;
}
button:focus {
border-radius: 6px;
outline: none;
box-shadow: 0 0 0 2px white, 0 0 0 4px blue;
}
<button>Button</button>
