Nice one! But like in your older version, you should make a change for IE10 compatibility in line 11:

:root input[type="checkbox"].ios-switch + div { padding-left: 0; ... }

IE10 can't transition from a not-given value to something.

BTW: I'm doing the same without any JS additions by transitioning a transparent border width of the container and having the switch positioned absolute:

It works, but it's not as smooth in Firefox on my machines. Chrome and IE10 are buttery smooth.

This is a grate solution, exactly what I was looking for a project of mine. Can you tell me what license apply to this code?

Suggestion, can you add:

box-sizing: content-box;

to line 12? It doesn't work correctly when box-sizing: border-box is on.
