Tried following CSS : button + label {background: yellow;} button:focus + label {background: green;} Result is not OK on Chrome 23 (label must be green on button click) see : http://codepen.io/raphaelgoetter/pen/fLGow
I think that this is a duplicate of bug 22261. Label becomes green when the button is actually focused. just not when it's clicked. *** This bug has been marked as a duplicate of bug 22261 ***
