Hi, I have some checkboxes with the <input> inside the <label> ( e.g. the 'Create Account' button on (logged out) Woocommerce Checkout page).  I don't wish to change the markup but after many hours of trying I can't get them to work.  I can do the CSS but the checkbox doesn't respond when clicked.  What am I missing ?

The markup:

<p id="checkbox1_field">
  <label class="checkbox">
    <input type="checkbox" class="input-checkbox " name="checkbox1" id="checkbox1">
    Classic checkbox
   </label>
</p>

Thanks

G
