I have:
<label class="checkbox-container" for="terms">I agree
with the Terms and Conditions</label>
<input class="checkbox required" id="terms" name="terms" type="checkbox">
I want the label's ::before color to change to red, when the error class on input is called. For live preview checkout: http://apespark.com/formifyPro/examples/register.html
I have no idea how to specify this in CSS and design this specific case-scenario.
