+ * We want to hide the checkbox in lieu of the toggle-btn
+ * "slider toggle". We need to make the toggle keyboard
+ * focusable, however, which is not possible if it's
+ * display:none. We work around this by making the toggle
+ * invisible but still present in the display list, allowing
+ * it to receive keyboard events. When it is focused by keyboard,
+ * we use the -moz-focusring selector on the invisible checkbox
+ * to show a focus ring around the slider toggle.
