Checkbox hack for hide/show

To use checkbox as a toggle for hiding and showing content, apply the class u-chkbx-toggle to the checkbox

<input type="checkbox" id="other" name="other" class="u-visuallyhidden u-chkbx-toggle">

and the class u-chkbx-toggleReceiver to the element you want to show and hide

<div class="u-chkbx-toggleReceiver">
   Content to show
</div>

The CSS rules that defines this beahvior is in: src/sass/07-trumps/_trumps.utilities.scss and can be improved.

Here a complete example code:

<div>
    <input  type="checkbox"  id="other"  name="other"  class="u-visuallyhidden u-chkbx-toggle">
    <div class="u-chkbx-toggleReceiver">
        Content to show
    </div>
</div>

Important: remember to wrap the code in a <div> for a better control.
