Removing checkbox inputs from specific class

Greetings,
I have a specific form on my site that contains checkboxes, and I would like to hide the actual checkboxes. The css class for the checkboxes on this form is .checkstyle (css below).

I could use:
input[type=checkbox] { visibility: hidden;}
but that removes all checkboxes on the site, and I only want class checkstyle to be hidden.

Any suggestions?

Thanks,
Nate

.checkstyle + label{
background: #ffffff;
height: 50px;
width: 105px;
color: #70962d;
text-align: center;
padding: 15px 25px;
}

.checkstyle:checked+label {
background: #70962d;
height: 50px;
width: 105px;
color: #ffffff;
text-align: center;
padding: 15px 25px;
}
