Toggle Active state

There are two parts to a toggle. There is the “track” (which you currently have as the blue), and there is the “switch” (currently in white).

In order to do what you want (blue track for “off”, black for “on”), you can add the following CSS to the Custom CSS section of the styler addon.

.hdq_row .hdq-options-check input[type="checkbox"]:checked + .hdq_toggle:before {background: #000000 !important;}

You can remove the :checked part of the above if you wanted to affect the “off” state.
