How do I stop the checkbox appearing, so it is slider only

I'm using slider 3 from here:

It is the "On/Off" Slider, I have copied the HTML and CSS. Everything is working as it should, however on my webpage the "Checkbox" is still visible along with the On / Off slider, please see:

I appreciate your help.

Thanks
