Hi,
the toggle has basically two properties.
I've assigned the "ToggleMe" class to the Toggle Widget to control it's background color and the font color. The style sheet like this:
.ToggleMe {
color: #2379FF;
background-color: transparent;
}
For the actual background you can use
.toggle.toggle-assertive input:checked + .track {
border-color: green;
background-color: green;
}
Despite it's being a bit too green, it works quite nice.
One controls the actual track color, the other the border around the Widget.
(It will be for ALL Toggle Widgets you're using though)
I hope that helps
Cheers
/Michael
